Mercedes-Benz GLB Radio Replacement Parts

The Mercedes-Benz GLB (X247) launched in 2019 and remains in production, with a facelift arriving in 2023 that brought updates to the infotainment system and MBUX software. Radios from pre-facelift cars (2019–2022) and post-facelift cars (2023 onwards) may differ in hardware and software configuration, so crossing that boundary is something you should confirm with the breaker against your registration. Within either generation, radios are generally consistent, but always verify the part matches your exact build.

The 2023 model year marks the GLB facelift, which introduced revised MBUX infotainment hardware, so a radio from a 2020 pre-facelift car may not be a straight swap into a 2023 post-facelift car. Name the boundary to your breaker — pre-facelift (2019–2022) versus post-facelift (2023 on) — and ask them to confirm compatibility against your registration before buying. Never assume a radio will plug straight in across a facelift without checking.

For the GLB, trim levels such as Sport, AMG Line, and AMG Line Premium do not fundamentally change the radio unit itself, so the trim the donor car came from is not the key compatibility factor. That said, higher trims may have been fitted with upgraded or optional infotainment systems — such as a larger screen or additional features — so the specific unit spec matters more than the trim name. Check the part number on your existing unit and ask the breaker to match that, rather than going purely on trim level.

Mercedes-Benz vehicles from the same era often share MBUX infotainment architecture across models such as the GLA, GLC, and A-Class, which can mean radios are physically and electronically similar. However, software configuration, screen sizes, and connector layouts can vary between models, so a unit from another Mercedes is not guaranteed to be a drop-in fit. Describe your GLB's exact setup to the breaker and ask them to confirm the donor unit's origin and part number before purchasing.

No — the engine or gearbox fitted to your GLB does not affect radio compatibility. What matters is the generation of the car (pre- or post-facelift), the specific infotainment system fitted, and the part number of the unit. Focus on matching the screen size and system spec rather than the powertrain when talking to a breaker.

Give the breaker your full registration number so they can look up your exact build, and note whether your car is a pre-facelift (2019–2022) or post-facelift (2023 on) model if you know. It also helps to photograph or note the part number on your existing radio, as well as your screen size, since GLB infotainment was available in different configurations. The more detail you provide, the better the breaker can match the correct unit and avoid compatibility issues.
