I am not experiencing any disconnects but after five minutes I get a broken up screen display on my Mercedes GLC. There are lots of people experiencing this problem and the common denominator appears be Mercedes and iPhone 17 Pro max. I got a software update from apple yesterday so am hoping when I test it today they have resolved the issue. I still have my iPhone 15 which works perfectly with the car. If it is not resolved this week I am returning my iPhone 17 pro max. It makes no difference if I connect wirelessly or with a cable.
