I've a Peugeot 2008 and the navigation, etc. worked well with the lighting to USB cable when I had an iPhone 12 Pro Max. I've just upgraded the phone to the 15 Pro Max and it no longer works even though I'm using an Apple USB-C to USB cable. The experience upgrading to the 15 has not been a happy one; not only can't I use it properly in my car, the transfer of data from the old to the new phone also transferred over some glitches in the settings (which no-one seems able to find) which mean that the Mail app does not display emails (particularly those pulled in from Gmail) and - even though the ringer and notifications are turned on - there is no announcement/ringing for incoming calls, texts, etc.
