Apple CarPlay connection issues with new iPhone 15 pro

May need to check and see if there is an update for your car head unit. I haven’t had any issues with any of my vehicles but they aren’t Honda’s. Also check Honda user forums to see if others are having the issue. Every time a new device or iOS comes out it seems some cars have issues (personally never have). Sometimes it’s something that the manufacturer needs to address with a firmware or software update. Is your CarPlay wireless or wired? Do you have access to another car that also has CarPlay? If so, check to see if you can connect to it. If you can then it lets you know the issue is likely specifically with your car head unit.

Are you using the USB-C cable that came with the phone? It’s possible that an older cable or some 3rd party ones may not work properly. Is the port in your car USB-C or are you using an adapter or USB-C to USB-A cable? I use wireless CarPlay but will try plugging mine in later today to see if I experience any issues…just to see if there may be a wider issue with wired connections.
