2022 Wrangler Rubicon with the same 8.4” Uconnect (Made by Alpine). iPhone 15 Pro. iOS17.0.2. Spent 2 hours on the phone with Apple Support today. USB C to USB C cable that came with the iPhone doesn’t enable it to be seen for CarPlay, though it does charge. I have a 3 year old Mophie USB A to USB C cable that SOMETIMES enables CarPlay. However, if I turn the engine off, getting gas, then turn on again, CarPlay is no longer enabled.
I had an iPhone 14 Pro connected by an Apple USB A to lightning cable that worked flawlessly for a year in the Jeep.
Apple acted like they have had no reports of CarPlay problems with iPhone 15. Obviously, that is not true by reading the numerous posts in this Support Community. Also, suspiciously, on Sept. 20, Apple Store added an overpriced ($29) USB C to Lightning adapter and specifically lists it for use with Apple CarPlay! I have ordered it and hope it will resolve the issue (arrives in 2 days). Will post the outcome. And if it doesn’t work, I will be returning it.
