If you own a Mercedes GLC and want to know what to buy first, start with a set of custom-fit all-weather floor mats, then add a boot liner, a screen protector and a phone mount. That order protects the two surfaces that cost the most to repair and fixes the two annoyances owners complain about most. Everything else on this list is optional.
The reason that answer is short is that GLC accessory buying has one gate you have to pass first: the generation. The X253 chassis code covers the Mercedes GLC sold from 2016 through 2022, and the X254 and C254 codes cover the GLC from 2023 onward. Those two generations do not share trim, mats, screen shapes or console geometry, and a listing that never says which one it fits is a listing you should walk away from.
That is the single biggest problem we see with the best Mercedes GLC accessories. Owners buy a part for the wrong year, it arrives, and it sits in a corner of the garage next to the last two things that did the same thing. We read through the owner forums for this topic and the pattern repeats constantly: fitment confidence matters more to GLC owners than any other factor, and the forums are full of people asking where to buy accessories that are not generic marketplace listings.
So the six picks below each carry an explicit generation tag, an honest note on what they do not do well, and a link to check the current price. Three cover the older X253 cars, three cover the newer X254 and C254 cars. We kept the list short on purpose. Six things you will actually use beats a catalogue of forty things that will not fit.
If you are shopping a different vehicle, our guides to the best Rivian accessories and the best Cybertruck accessories follow the same fitment-first logic, since both of those vehicles also changed generation recently.

1. KELCSEECS Floor Mat and Cargo Liner Set for X253 – The One Every GLC Should Buy First
KELCSEECS Floor Mats & Cargo Liner Custom for Benz GLC 250 | 300 | 350e 2022-2016 (Not for Coupe) Car Mats Automotive Cargo Mat Floor Liners Trunk Mat GLC All Weather Trunk Liner
Fits 2016-2022 GLC
TPE material, not rubber
29 x 22 x 6 inch footprint
Vehicle-specific 3D scan
Pros
- Vehicle-specific 3D-scanned cut that clears pedals and seat rails
- TPE stays flexible in extreme cold
- Raised edges trap water salt and snow
- Rinses clean with water
Cons
- Does not fit the Coupe body style
- Trunk piece may need warming to lay flat
- X253 only
- not the 2023-plus GLC
This is the accessory to buy first on an X253, and the reason is simple. The carpet in a GLC is the most expensive interior surface to replace, and road salt, winter grit and dog hair attack it from the moment you drive off the lot. A 3D-scanned set drops straight into the footwells and covers the boot floor as one matched system rather than leaving you with loose mats that slide around on corners.
The material is thermoplastic elastomer, not traditional rubber, and the difference shows up in January. Reviewers consistently single out the fact that the TPE stays supple in deep cold instead of going stiff and cracking, and several mention that the mats can simply be rinsed under a hose to reset them. Our team has handled several sets of this type and the raised lip is the feature that matters: it is what turns a spilled coffee from a carpet replacement into a thirty-second cleanup.
Fitment is the reason this sits at number one and the reason it will save you the most money if you get it right. The 3D scan is vehicle-specific, and the anti-slip backing is shaped so it does not foul the pedals or the seat guide rails, which is the single most common complaint about universal mats. If you have ever had a mat creep forward under the brake pedal, this design was built to end that.
It is also the highest-rated product in this list by a wide margin, with thousands of reviews backing up the claims above. The one thing worth doing before you order is to confirm the year range on the listing matches your car, because this set is cut for the 2016 to 2022 GLC only. Owners of the Coupe body style need a different footprint, and the standard SUV and the Coupe do not share one.
Who should buy these mats
Buy these if you drive in a climate with rain, snow or road salt, which covers most of the country for at least part of the year. They are equally worthwhile if you have children, pets, or a job that puts tools in the car, because the raised edges contain whatever ends up on the floor rather than letting it soak in. Anyone who cares about resale value should count them as cheap insurance, since stained carpets are one of the first things a used-car buyer notices.
Where these mats fall short
The main limitation is generational rather than quality: these are X253 mats, and they will not fit a 2023 or newer GLC. Second, a recurring note appears in reviews about the cargo section needing heat or a flip to lie perfectly flat after it comes out of the box, which is a ten-minute fix rather than a real defect. If you need something for the newer generation, pick two in this list instead.
2. Powerty 3D TPE Floor Liners for the 2023-2025 X254 – Best Fit for Newer Models
Powerty Floor Mats for 2023 2024 2025 Mercedes Benz GLC?GLC 300?GLC 350e?4Matic All Weather 3D TPE Anti-Slip Car Liners for 1st & 2nd Row Accessories
Fits 2023-2025 GLC
Front and rear rows covered
Operable -40F to 122F
30 x 20 x 5 inch footprint
Pros
- Precise 3D-scanned cut that drops in without trimming
- Flexible odorless TPE that resists reshaping
- Raised edges protect carpet from spills
- Rinses clean under water
Cons
- Rear and trunk mat is less precise than the front
- Some variants lack rear floor vent cutouts
- X254 only
- not the 2016-2022 GLC
If your GLC is a 2023, 2024 or 2025 model, this is the set to start with. The newer X254 interior is shaped differently at the sills and the seat rails, so mats designed for the older car either leave gaps or interfere with the seat tracks. This one was scanned against the newer body specifically, and the front mats drop in with no trimming at all, which is not something you can say about most liners in this category.
The temperature rating is the detail we liked most. The material is specified as operable between minus 40 and 122 degrees, and that range matters more in a compact SUV than in a sedan because the footwells on an X254 sit high and heat up quickly at idle. Reviewers also note the material is odorless out of the box, which is a genuine improvement over cheaper rubber mats that smell for weeks.
What separates this from a generic liner is the raised perimeter. It is a low lip, but it is continuous, and it does the job of keeping sand, coffee and snow melt on the mat surface where you can rinse it away. Several owners compare the weight and feel favorably to established name-brand mats, which tells you the material is in the right league even before you consider how it handles a hard winter.
One practical note for anyone ordering: the set arrives folded, and owners report that leaving the pieces in the sun for a short while flattens the creases so they sit flush. We would do that before the first drive rather than live with a rumpled mat under the pedals. The overall rating here sits a little below the KELCSEECS set, and the gap traces almost entirely to fit precision on the rear pieces rather than to the material itself.
Who should buy these liners
These are the right liners for anyone with a 2023 or newer GLC, including the GLC 300, GLC 350e and 4Matic variants, and they cover both the first and second rows. Owners who carry a dog, walk a dog, or deal with beach sand and ski equipment will appreciate the raised edges more than most, because the containment is what stops grit migrating into the seat rails where a vacuum will never reach it.
Where these liners fall short
Fit on the rear and trunk pieces is described as occasionally less precise than the front, so measure your boot floor lip before you rely on the cargo section for spill protection. A minority of variants also lack cutouts for the rear floor heat vents, which matters if you have heated rear seats. And like the first pick in this list, these do nothing for an X253 car.
3. UKTOP Windshield Sun Shade for 2023-2026 GLC and GLK – Cheapest Upgrade That Pays Off
for Mercedes Benz GLC 260 GLC 300 GLK-Class 2023-2025 2026 Sun Shade
Fits 2023-2026 GLC and GLK
250T fabric with nano coating
Blocks 99.79% UVA and 99.95% UVB
Silver, one-sided
Pros
- Spring hoop frame keeps the shade taut with no gaps
- Thin and light enough for the supplied pouch
- Works with a dash cam or camera housing
- Covers side windows as well as the glass
Cons
- Springs open quickly during unfolding
- Stiff to fold back into the pouch
- Silver finish is one-sided only
A sun shade is the least glamorous item on this list and the one we would buy first on a car that lives outside. Dashboard surfaces and screens in a parked GLC reach damaging temperatures in summer, and the leather on a GLC’s dash is a known weak point. This shade is vehicle-specific for the 2023 through 2026 GLC and GLK, and it uses a double D-shaped spring steel ring rather than the accordion pleats that leave gaps at the edges.
The fabric is 250T high-density material with a nano coating and four anti-UV layers, rated to block 99.79 percent of UVA and 99.95 percent of UVB at an SPF of 100. Those numbers are manufacturer figures, but the practical reports line up: owners say the cabin is noticeably cooler on return and the shade holds full tension with no light gaps around the edge. It also folds to about pocket size and comes with a pouch, so you can leave it in the boot permanently.
The hoop design solves a problem that hard-mount shades create on modern Mercedes. A GLC with a camera housing or a dash cam mounted above the screen blocks a traditional flat shade from sitting flat against the glass. This one can sit at an angle and still cover effectively, and owners note you can drape it across the side window for full shade on a low sun. That flexibility is what separates it from the cheapest shades in this category.
On balance this is a low-cost item that delivers more than a cosmetic accessory usually does, which is why it makes the top three even at the bottom of the price range. If you are gifting a GLC accessory to someone, this is the safest choice in the list because the fit is generation-specific and the downside of getting the era wrong is a shade in a drawer rather than a part you cannot fit. The same reasoning applies if you are not sure which generation your family member owns.
Who should buy this sun shade
Anyone who parks outdoors in a hot climate, and that includes most of the southern and western United States. It also earns its place for resale protection, since a faded or cracked dashboard is a common reason buyers walk away from an otherwise clean GLC. If you use your car for long road trips in summer with children or a dog in the back, the cooler cabin is the selling point rather than the paint protection.
Where this sun shade falls short
Two things to know before you buy. The spring ring means the shade can pop open the instant you unfold it, so handle it facing away from your face and lay it onto the glass rather than pulling it out fast. It is also stiff enough that folding it back into the pouch takes practice the first few times. The silver coating is one-sided, so it works as a sun shade and not as a low-profile cover for frost.
4. Karltys Tempered Glass Screen Protector for the 11.9 and 12.3 Inch Screens
[Upgrade] 2 Pack Mercedes Benz GLC 11.9-Inch & 12.3-Inch Screen Protector for Models GLC 300 2023-2025 2026/W206 C300 2022-2025 2026/AMG C43 2023-2025 [No Glare & Fingerprint] Tempered Glass Mercedes Benz Accessories
Two pieces, 11.9 and 12.3 inch
9H hardness tempered glass
Anti-glare matte surface
12 x 11 inch sheets
Pros
- Cut dimensions match the GLC screens closely
- Matte finish cuts glare in direct sun
- Fingerprint resistant and touch stays responsive
- Installs in seconds with no bubbles or residue
Cons
- Only fits screens with a physical button bezel
- Matte finish dims the display slightly
The newest GLC interiors put two large touchscreens within reach of everything in the cabin, and both of them are vulnerable. This pack covers the 11.9-inch portrait centre display and the 12.3-inch digital instrument cluster with 9H hardness tempered glass, which is the same grade used on phone screens. On a GLC the screens take far more punishment than a phone because keys, bags and dog leads reach them constantly.
The anti-glare matte finish is the feature we would emphasise for anyone in a bright climate. A glossy screen on an X254 turns unreadable in direct sun because the cabin reflects off it, and a matte layer handles reflections without adding a visible haze to the image. Owners also report that the touch response stays responsive and the protector is effectively invisible once fitted, which matters in an interior that is otherwise full of glossy piano-black surfaces.
![[Upgrade] 2 Pack Mercedes Benz GLC 11.9-Inch & 12.3-Inch Screen Protector for Models GLC 300 2023-2025 2026/W206 C300 2022-2025 2026/AMG C43 2023-2025 [No Glare & Fingerprint] Tempered Glass Mercedes Benz Accessories customer photo 1](https://www.minormania.com/wp-content/uploads/2026/09/B0C5R3QTRQ_customer_1.jpg)
Installation is the easiest job on this list. There is no adhesive residue and no bubbling according to the reviews, and most people report a couple of minutes per screen including cleaning the glass first. That matters because a screen protector that is fiddly to fit gets fitted badly or not at all, and a badly fitted protector with trapped bubbles is worse for glare than no protector. These are designed to be reapplied if you do get a bubble.
The important caveat is that this pack is cut for screen configurations that have a physical button on the bezel. If your particular screen layout does not match, the cut will be wrong. That is where the small share of one-star reviews comes from, and it is the only reason the average rating sits where it does. Confirm your screen shape against the product description before ordering rather than assuming every GLC screen is the same.

Who should buy this screen protector
Buy it if you drive with a passenger who uses the navigation screen, or if you routinely put keys and bags in the front of the cabin. It is also worth adding if your GLC is fitted with the 360-degree camera and parking sensors, because a system you rely on should not be compromised by a scratched or fogged display. Owners who work the car for a living and use the centre screen all day are the happiest with the matte finish.
Where this screen protector falls short
Two honest limits. It only fits screens that have a physical button bezel, so verify your screen layout first. And a minority of owners feel the matte coating dims the display very slightly, which is the trade every anti-glare protector makes. If you care more about colour saturation than about reflections, a clear glossy protector may suit you better.
5. MaserWeller Magnetic Phone Mount for the 12.3 Inch Cluster – No Vent Clip
Car Phone Holder for Mercedes-Benz GLC/CLE/C-Class 2023-2026,12.3″ Screen
3D-scanned for 2023-2026 GLC
20 N55 magnets, black aluminum
5.5 ounce mount
15.4 x 1.5 x 4.6 inches
Pros
- Snug 3D-scanned fit that stays put over bumps
- Strong enough magnet for large phones
- True one-handed attach and release
- Removable and non-destructive install
Cons
- Can cover part of the upper dash chrome trim
- Plastic frame feels slightly cheap beside the magnet
Phone mounts are the most requested GLC accessory on the owner forums and the most commonly regretted purchase, because most of them clip onto a vent. Vent clips rattle, block airflow, and on a GLC they often sit in front of a screen. This one avoids the problem entirely by mounting to the 12.3-inch digital instrument cluster, which is 3D-scanned for the 2023 to 2026 GLC and also fits the 2022 to 2026 C-Class and 2024 to 2026 CLE.
The magnet is the part that earns the money. Twenty N55 neodymium magnets give a MagSafe-style hold that owners say stays put over potholes, speed bumps and hard cornering, and the head is black aluminum rather than the flimsy plastic most mounts in this bracket use. It also works one-handed, so you glance at navigation without taking your attention off the road for longer than a single glance.
Two details make this easier to live with than it looks in photos. The height is adjustable, so you can set the phone below the line of sight rather than in it, and the package includes a magnetic ring so phones without MagSafe still hold. The installation is non-destructive and reversible, with double-sided tape included but optional, so nothing is permanently stuck to the cluster. Several owners mention that the included metal stem upgrade improved an earlier version that felt flimsy.
The compromise is cosmetic, and owners say so directly. Depending on your dash, the mount can overlap part of the upper chrome trim, which some people notice and others never register. Because it attaches to the instrument cluster rather than a fixed surface, check the fit against your model year before committing, since a minority of reviews report a mismatch on a specific year. If you can accept a small overlap on the trim, this is the most stable mount we found for the newer interior.
Who should buy this phone mount
Anyone who navigates with their phone in a city, on a mountain route, or anywhere with easy-to-miss turns. Drivers who take calls hands-free benefit as much, because the one-handed release means you do not have to hunt and grab while the phone slides off a vent clip. It suits anyone who has already tried a vent-clip mount and given up on it, which is a very large group of GLC owners.
Where this phone mount falls short
It is an X254-era part, so it does not cover the 2016 to 2022 GLC dashboard. The plastic frame feels cheaper next to the aluminum head, and the mount can cover part of the upper dash chrome trim depending on your interior. It is also the least-reviewed product in this list, so treat the fit feedback as good rather than proven across every model year.
6. Karltys Center Console Cover for X253 – Storage and Scratch Protection
Karltys Center Console Cover for 2015-2021 Mercedes Benz C Class C300 W205 /2016-2022 GLC Class /2019-2024 EQC, Anti-Scratch Leather Waterproof Armrest Console Cover with Storage Pockets (Black)
Fits 2016-2022 X253 GLC
PU and PVC leather, soft and odorless
15.5 ounce cover
13.7 x 13.11 x 1.65 inch package
Pros
- Soft material that is not hot in summer or cold in winter
- Adds two side pockets for phones and glasses
- Finish does not look cheap
- Shields the console from sunscreen and pet claws
Cons
- Elastic anchoring can work loose over time
- Added bulk can restrict the console lid
- No printed instructions and fiddly first fitting
The center console armrest on an X253 takes a beating that nothing else in the cabin sees. Sunscreen, coffee, dog claws, keys, and a decade of fingernails finding the same spot will all wear the original surface. This cover is cut for the 2016 to 2022 GLC, plus the C-Class W205 and the EQC 400, and it is a genuinely useful upgrade on an older car where the original console is already showing its age.
The storage is the part that surprises people. Two deep side pockets appear along the armrest edge, and reviewers mention using them for a phone, glasses, pens and tissues, which takes a lot of clutter off the center of the cabin. The material is soft breathable PU and PVC leather described as odorless and soft to the touch, and the comfort point is real: an armrest that is not hot in July or cold in January is a small daily quality-of-life change.
Installation is thread-through rather than clip-on. Elastic straps run through the gaps around the console panel, so there is no adhesive and no drilling, and it comes off cleanly if you want to resell the car. The finish is where this beats the cheapest console covers on the forums, where owners complain about rattles and plastic that looks visibly mismatched against a Mercedes dash. This one reads as a fitted cover rather than a slip-on sleeve.
It does also share that platform with the C-Class W205, so if your household has both cars, one cover covers both. That is worth knowing because it extends the useful life of the purchase. Set expectations on the physical tolerances, though: the elastic anchoring is the part most likely to need re-hooking after a few months of use, and the extra thickness is real enough that some owners find the console lid no longer opens fully.
Who should buy this console cover
It suits X253 owners whose console is already scuffed, or whose interior is a light colour that shows every mark. Parents and dog owners get the most out of it, both because of the added pockets and because it stands between claws and the original console surface. Buyers who plan to keep the car for several years and resell it will find the wear protection worthwhile on its own.
Where this console cover falls short
Fit is limited to the 2016 to 2022 GLC, so it does nothing for a 2023-plus car. The elastic hook can work loose over time and may need re-hooking, the added bulk can stop the console lid opening fully on some cars, and there are no printed instructions, so expect to work out the threading yourself the first time.
How Old Your GLC Is Changes the Whole List
Owners of older X253 cars are in the best position of the three groups, because the accessory market for that generation is mature and plenty of parts are still produced. A car built in 2016 or 2017 needs protection more than a new one does, because the paint, the carpet and the console have already taken ten years of weather and use. Owners of a 2023 or 2024 car have the newest electronics to protect but fewer dedicated-fit accessories in circulation, so early buyers sometimes have to settle for a universal piece.
There is also a category most guides skip. A newer GLC already carries a powered tailgate, keyless entry, an 11.9-inch portrait touchscreen, a 12.3-inch digital instrument cluster, dual-zone climate, 64-colour ambient lighting, a 360-degree camera, parking sensors, blind-spot radar, a fingerprint scanner, a digital key and a 5G module on many trims. Accessories that duplicate those functions are the most common wasted purchase we can see from a distance.
How to Verify GLC Accessory Fitment Before You Buy
The fastest way to avoid a wrong-generation purchase is to buy by chassis code, not by marketing name. A listing that says it fits the GLC 300 without naming a year range is telling you nothing useful, because the GLC 300 has been sold in both generations with completely different interiors. X253 means 2016 through 2022 and X254 or C254 means 2023 onward, and parts do not interchange between them even where the trim looks similar.
For genuine Mercedes parts, the most reliable check is your VIN. A dealer or a parts counter can confirm whether a part number fits your car, and that check takes a phone call. It also tells you whether the part is OE genuine, which is the category that carries a factory warranty and the one that will always match the trim finish. Our experience is that this is the single most responsible thing you can do before spending on any GLC accessory.
Aftermarket and OEM-equivalent parts are harder to verify, which is why the year range on the listing is the only signal you get. Look for a stated model range, check the product photos for the screen or console shape, and read the one-star reviews rather than the five-star ones, because fit failures cluster there. The general rule is that a listing claiming to fit everything is not telling you anything.
Sourcing terms matter too. OE genuine parts come from Mercedes and match exactly. OEM-equivalent parts are made by the same factories under other brands, which is why they are common for mats and liners. Aftermarket parts are independent designs, and they range from excellent to the cheap trim owners complain about on forums, where rattles, mismatched finishes and adhesive damage to dash surfaces are recurring themes. We would skip any accessory that claims to stick permanently to a soft-touch dashboard surface.
Install difficulty on this list is pleasantly low. Mats, the cargo liner, the sun shade, the screen protectors and the console cover are all clip, lay or thread-in items that take under ten minutes each with no tools and no disassembly. The phone mount is the only one that takes a moment, because it has to be positioned on the instrument cluster and set to a height that does not block your view of the road. Nothing in this list needs a panel off, which is the point. If a listing asks you to trim, drill or remove interior trim to fit it, that is not an accessory any more.
Some categories are worth buying as bundles rather than piece by piece. A winter and mud setup is the floor liner set, a boot liner and a set of all-season sill protection, which between them contain everything the British and northern weather throws at a car. A road-trip setup is the mats, the sun shade, a phone mount and a boot organiser so the back seat stays usable. A dog setup is the cargo liner plus a guard behind the rear seats, since an X253 cargo liner will not stop a dog pushing a damp paw across the back of the cabin.
Know what to avoid. We would skip any trim piece advertised as sticking permanently to a soft-touch dashboard surface, because the adhesive outlasts the accessory and leaves a mark that lowers resale value. We would skip accessories that claim to fit all GLC years without stating one, because that claim is never true. And we would skip a phone mount that clips to a vent in a car with a screen mounted directly behind it, which is exactly the arrangement a GLC has.
Last, check what your car already has. A newer GLC comes with a 360-degree camera, parking sensors, blind-spot radar, an 11.9-inch centre display, a 12.3-inch cluster, a powered tailgate, 64-colour ambient lighting and a wireless charging pad on many trims. If you are about to buy an accessory that performs a function your car already has, save the money and spend it on protection instead. Our Kia Telluride accessory guide covers the same problem of duplicate purchases in a different segment.
Frequently Asked Questions
What should I buy first for my Mercedes GLC?
A set of custom-fit all-weather floor mats plus a boot liner is the correct first purchase, because it protects the most expensive interior surfaces from salt, mud and spills at no permanent cost to the car. Add a screen protector and a magnetic phone mount second, since those fix the two annoyances owners raise most.
Are GLC accessories compatible across model years?
No. X253 covers the 2016-2022 GLC and X254 or C254 covers the 2023-present GLC, and parts do not interchange between the two. Floor mats, screen protectors, console covers and phone mounts are all generation-specific, so always confirm the chassis code before buying.
What are the most popular Mercedes GLC accessories?
The most popular additions are all-weather floor mats for the correct generation, a boot liner, a windshield sun shade, screen protectors for the 11.9-inch and 12.3-inch displays, a magnetic phone mount, and a center console cover on older cars. Protection items outsell cosmetic trim in almost every owner forum we read.
What accessories are available for the Mercedes-Benz GLC 300?
The GLC 300 was sold in both generations, so availability depends on the year. For 2016-2022 X253 cars you will find custom-fit TPE mats, a cargo liner and a center console cover. For 2023-2025 X254 cars you will find 3D TPE liners, a sun shade, tempered glass screen protectors for both displays, and magnetic mounts for the 12.3-inch cluster.
Will aftermarket accessories void my Mercedes warranty?
Accessories that alter the vehicle or interfere with connected services can affect warranty coverage for the affected system, but simply adding a floor mat, sun shade or screen protector does not. The items to be careful with are anything electrical that taps into the wiring, anything permanent that damages a surface, and anything mounted where it could block the 360-degree camera or parking sensors.
What are the most useful GLC upgrades for daily driving?
The most useful daily upgrades are the ones that remove friction: custom-fit mats so grit stops reaching the carpet, a sun shade so the cabin is not punishing on a hot day, a screen protector so the displays stay readable, and a phone mount that does not rattle or block a vent. Cosmetic trim is the least useful category unless you enjoy the work.
What to Buy First and What Can Wait
In the first month, buy protection and nothing else. On an X253 that means the 3D-scanned mat and cargo liner set, and on an X254 it means the equivalent TPE liners for the correct years. A sun shade goes in the same order because it costs little and defends the dashboard and screens through every summer you own the car.
Across the first year, add the interior tech: screen protectors for the 11.9-inch and 12.3-inch displays, and a magnetic phone mount on the newer cars that fixes the vent-clip problem for good. The console cover belongs on this list too if your X253 console is already scuffed or if you share the car with a dog.
What can wait is everything cosmetic. Trim overlays, mirror caps and grille accessories are cheap and reversible, and they are the easiest place to end up with rattles, mismatched finishes or adhesive that damages a soft-touch surface. The same goes for anything that needs to be hardwired into the car’s wiring, which is where warranty and battery questions start to get complicated. Buy the best Mercedes GLC accessories in generation order, check the chassis code before you pay, and each pick here will do exactly what its description says.
