ive done it all , sometimes it will work for a bit then it fails in that siri dosent work
Wow, this all sounds quite frustrating. I have an iPhone X, running 12.3.1, and it’s on Verizon, and CarPlay (and Siri) work fine on my Elite AWD. I listen to Podcasts, use Maps, and Siri to dictate and read text messages while I”m driving. I don’t talk a lot while driving, but when I do, I don’t have any mic or cutout issues. Siri’s responsiveness depends on the quality of the LTE connection, but that’s an issue whether I’m in the Passport or not. Sometimes the initial connection doesn’t work the first time, and I’ll have to unplug/replug it in. Also, CarPlay activates less consistently if I have the iPhone plugged-in before starting the car — I usually wait until the head unit is up and running before plugging-in the phone. Incidentally, Siri also works when on Bluetooth by pressing the talk button on the steering wheel. I don’t think the Passport supports wireless CarPlay, but I haven’t messed with that.
... now, if I could only get Apple Music to quit randomly deciding which music to leave on my iPhone (and iPad/Macs), and which music to stick back into the cloud, I’d be much happier
Good luck with CarPlay issues and please keep everyone posted with whatever solution fixes is.
