What to know before buying

Requires a vehicle with existing factory-wired CarPlay or Android Auto and a compatible phone. The listing gives iPhone iOS 10+ and Android 11+ requirements, and recommends confirming wired CarPlay works using a cable before purchase. Its USB-C-only installation means the car's connection must also suit the adapter.

Listing details to confirm

The title and headline feature text describe both CarPlay and Android Auto, while the detailed setup instructions specifically describe connecting an iPhone for CarPlay. Confirm Android Auto operation and the selected listing's phone and vehicle compatibility before buying. The listed control methods do not establish that every control method applies to the adapter itself.

Who is it for?

A good fit for

Drivers with a compatible vehicle that already supports wired CarPlay or Android Auto and has a suitable USB-C connection.
Drivers who want to leave their phone free of a wired CarPlay cable and prefer a compact adapter.

Less suited to

Vehicles without factory wired CarPlay or Android Auto.
Buyers whose car requires a USB-A adapter connection or who need the adapter to add CarPlay to a vehicle that lacks it.
