Mazda CX-30 Aerial Replacement Parts

Yes, the Mazda CX-30 is fitted with a roof-mounted shark-fin aerial as standard across all variants, covering AM/FM radio and typically GPS or DAB functions depending on specification. This applies to all engine options including the 2.0 petrol, 2.0 Skyactiv-X, and 1.8 diesel, as well as both front-wheel-drive and all-wheel-drive versions. So whether your CX-30 is a base SE-L or a top-spec Takumi, it will have had an aerial fitted from new.

The Mazda CX-30 launched in 2019 and received a mid-life update around 2022, which introduced some interior and equipment changes but the external body structure and roofline remained very similar. For the shark-fin aerial, which is mounted to the roof via a fixed base, fitment across that update boundary is plausible, but because the integrated connector and any internal amplifier wiring can differ between model years, you should confirm with the breaker against your exact registration before buying. Do not assume early and late CX-30 aerials are a guaranteed swap without that check.

Trim level does not fundamentally affect aerial fitment on the CX-30, as the shark-fin roof aerial is a body-mounted component and the same basic unit is used across the range regardless of whether you have SE-L, Exclusive-Line, GT Sport, or Takumi trim. That said, higher trims may include an integrated DAB or GPS element within the aerial base that lower trims do not, so the physical shell can look identical while the internal function differs. When sourcing a used aerial, confirm with the breaker that the specification of the donor car matches yours — particularly whether both cars have DAB or navigation — rather than worrying about trim names.

Mazda does use similar shark-fin aerial designs across several of its models, and there is a reasonable chance of overlap in the base fitting between the CX-30 and models like the fourth-generation Mazda 3 (which shares the same era and platform family), but this is not something that can be confirmed as a guaranteed cross-model fit. The roof curvature, base footprint, and internal connector can vary between models even within the same manufacturer's range. Ask the breaker to check the part number or base dimensions against your CX-30's registration before committing to a cross-model aerial.

Water ingress through a damaged shark-fin aerial base is a known nuisance on various modern cars and is worth addressing promptly to prevent headlining or roof lining damage. A used aerial from a breaker is a practical and cost-effective fix, and because the part is largely passive (especially if your car does not have an amplified or GPS-integrated unit), a good used example should work reliably. Make sure the breaker supplies the aerial complete with its base gasket or that you fit a new gasket on installation, as this seal is what prevents water getting in.

On the CX-30, aerials fitted to cars with DAB radio or satellite navigation often incorporate an active amplifier within the shark-fin housing, meaning they require a power feed via the connector rather than being a simple passive antenna. If your car has DAB or built-in navigation, you almost certainly need an amplified aerial to retain full functionality. Check your current aerial's connector — a passive aerial will typically have a single coaxial plug, while an amplified unit will have an additional wiring connector for power — and confirm with the breaker that the donor car's aerial matches your setup before purchasing.
