Wired CarPlay not working on iPhone 17 Pro Max running iOS 27

iOS 27 wireless CarPlay working but not wired


I have an iPhone 17 Pro Max and updated to iOS 27. My vehicle is a 2026 Subaru Forester Hybrid Touring. I am able to use CarPlay wirelessly but not wired. I have tried using a USB-A to USB-C cable and a USB-C to USB-C cable. Both are Apple branded cables but still no go with CarPlay, although they do charge the phone. I really do not want to keep using wireless CarPlay because it has disconnected at random times. Other people at work I have spoken to with Subaru models (not sure of model years) that have iOS 26 or older do not have wired connectivity issues. They have shown me in person that their wired connections work fine.

Check Settings > Privacy & Security > [scroll down to] Wired Accessories. Set to “Always Allow”.


The downside of this is you’re susceptible to “juice-jacking” if you use public iPhone chargers.
