If you wiggle the USB cable does it cut in and out? If so you need to clean your phone's port.Well it just started working again out of the blue. Cant say I did anything other than check see the fuse was seated...it was.
On start up it found the iPhone....I restarted the jeep twice yesterday and didn't
I did and tried multiple iPhones and different cables.Did you try cleaning the lightning port on your phone? I know sounds strange, but if you keep your phone in your pants pocket, lint will build up in the lightning port. The charging operation will power through the lint and charge the phone, but the data signals do not transmit reliably. Turn phone power off and use a wooden toothpick to clean out the lightning port. I had this happen a couple times and after cleaning, CarPlay connects and works perfectly.
