Digital cluster retrofit — Mercedes-Benz X156
Mercedes-Benz GLA Digital Cluster Upgrade
The SUV member of the compact trio - same cluster as the A-Class and CLA, so it adds coverage without adding a new part number to your shelf. A 12.3" 2400 x 900 panel, add-on cluster for the 2015-2019 cars: plug-and-play harness, CAN bus plug-in, no coding — and because the original mainboard stays in the car, mileage and service data are the car's own.
What you get
- 12.3-inch 2400 x 900 panel on an imported LCD
- Original cluster mainboard kept — every value on screen is read from the car itself
- Front and rear camera picture plus parking radar on the cluster itself
- 8 theme UIs and 32 switchable background colors
- Plug-and-play harness on the original connector - no wire cutting, no splicing, no pins to move
- CAN bus plug-in, no coding: factory data is read over the car's own bus
- CarPlay built in, instant switching back to the original view with no reboot
What it looks like
Fitment at a glance
Everything in this table comes from the fitment we quote from — if your car does not match a line, we will tell you before you order rather than after.
| Chassis | Model years | Panel | Factory system | Fitment type |
|---|---|---|---|---|
| X156 | 2015-2019 | 12.3" | NTG4.5 / NTG5.0 | Add-on cluster |
NTG4.5 and NTG5.0. Shared with W176 and X117.
Questions on this chassis
Does the higher dashboard of the GLA change the fitment?
No. The binnacle is the same as the A-Class; the bracket is what differs, and we ship the GLA one when you order for that car.
Are 4MATIC cars different?
No. Drive layout makes no difference to the cluster or the harness.
Can I test one unit first?
Yes. One unit ships at the same unit price as any larger order, nothing commits you to a second order, and a test unit leaves the factory in 3-7 working days.
Is coding or an odometer setup needed after fitting?
No. The original cluster mainboard stays in the car, so mileage, service intervals and warning data are the car's own. Nothing is coded, flashed or reset.
Will it fit the car in front of you?
Two questions and a photo is usually all it takes. The checker answers from the same table we quote from.
How it mounts
Add-on cluster — X156
The new unit mounts in front of the original cluster and covers it. On cars without a head-up display it sits in the HUD recess; on cars with the factory HUD it goes above the glovebox, so no storage space is lost and the original cluster stays untouched underneath.Time in the bay. Ten minutes. The cluster goes onto the factory connector through a plug-and-play harness, so there is nothing to code and no odometer to set up. A shop that swaps the cluster board instead keeps the car in the bay for 90 minutes or more, then adds flashing, coding and a mileage correction on top.
