Used Mercedes-Benz CLA Radio

The CLA runs across two generations: the first-generation C117 ran from 2013 to 2019, with a facelift in 2016, and the second-generation C118 launched in 2019. Radios within the same generation are generally the most likely to be compatible, but the specific head unit, wiring, and software version all affect whether a used unit will work in your car. Always confirm the part against your registration with the breaker before buying.

Both sit within the first-generation C117 CLA, but Mercedes updated the infotainment system at the 2016 facelift, so a pre-facelift radio and a post-facelift radio may not be a straightforward swap. Whether they interchange in practice depends on the exact head unit part number and the car's wiring loom. Confirm compatibility with the breaker using both your registration and the donor car's registration before committing.

This crosses the generation boundary between the C118 and the C117, and the two cars use different infotainment architecture, connectors, and control systems. It is very unlikely to be a plug-and-play swap, and we would strongly advise against assuming compatibility. Route this question directly to the breaker, who can check part numbers against both vehicles' registrations.

Trim level — whether Sport, AMG Line, or AMG Line Premium — does not generally determine whether a radio will physically fit, as the fitment is driven by generation, head unit type, and wiring rather than trim badge. That said, higher trims such as AMG Line Premium may have been ordered with upgraded audio systems like Burmester, which use different amplifiers and wiring, so the cosmetic and functional spec of the unit you receive may differ from your original. Confirm the exact head unit specification with the breaker against your registration to make sure you're getting a like-for-like unit.

Mercedes-Benz infotainment units often require coding or software adaptation after fitting a used unit, particularly if the car uses the COMAND or MBUX system. This is a question for a Mercedes specialist or the breaker, who may be able to advise on what is needed for the specific unit they are supplying. Never assume a used radio will be fully operational straight from installation without checking this first.

Mercedes has shared infotainment platforms across its compact car family — the A-Class, B-Class, and CLA have all used COMAND and MBUX systems — so there is sometimes parts overlap, but this is not guaranteed for every year or unit. Whether a specific unit from a donor car of a different model will fit yours depends on the part number, generation, and wiring compatibility. Check this directly with the breaker, quoting both vehicles' registrations, before purchasing.
