Second Hand Mercedes-Benz CLA Aerial

Yes, all variants of the Mercedes-Benz CLA are fitted with an aerial for radio reception. Most CLAs use a short fin-style 'shark fin' aerial mounted on the roof, which houses the AM/FM antenna and often integrates GPS and other signals depending on specification. This replaced the traditional mast-style aerial, so when sourcing a used part you should expect a shark fin unit rather than a conventional rod aerial.

The C117 (the first-generation CLA, built 2013–2019) and the C118 (the second-generation CLA, launched 2019) are entirely different body shells, and the shark fin aerials are unlikely to be a straight swap due to differences in roof profile, mounting points, and wiring connectors. These are distinct generation boundaries, so confirm directly with the breaker that the part number and connector match your exact registration before purchasing.

Trim level does not affect the fundamental fitment of the aerial itself — the roof-mounted shark fin unit is common across CLA trim grades including SE, Sport, AMG Line, and Edition trims. However, higher-specification cars may have additional signals integrated into the aerial module (such as DAB, GPS, or satellite), so the unit pulled from a lower-spec car may physically fit but could lack functionality your car relies on. Confirm with the breaker what signals the donor aerial supports against your own car's specification.

The C117 CLA received a facelift in 2016, but this update focused on styling, lighting, and interior changes rather than any significant revision to the roof aerial mounting or design. Aerials from pre-facelift C117 cars (2013–2016) and post-facelift C117 cars (2016–2019) are generally expected to be compatible, but confirm the connector and any integrated signal requirements with the breaker against your registration to be certain.

Mercedes-Benz models of the same generation often share platforms and body components, and the shark fin aerial housing or base plate may physically resemble units from the A-Class or other models. However, roof curvature, mounting hardware, and wiring connectors can differ even between closely related cars, so a direct swap is not guaranteed. Always ask the breaker to confirm compatibility with your CLA's specific generation and registration rather than assuming a Mercedes badge means it will fit.

Ask the breaker to confirm the part came from the same generation CLA as yours — C117 (2013–2019) or C118 (2019–onwards) — and check that the wiring connector matches, as differences in integrated signals (DAB, GPS, satellite) mean connectors can vary even within a generation. It is also worth confirming the colour or finish of the aerial if you want an exact cosmetic match, though repainting a shark fin unit is straightforward. Never assume fitment purely from year alone — always verify against your registration.
