Thanks guys, I will continue to monitor it and see if I can isolate it.
Lunatic59- My phone is not getting warm. It appears to be working fine. My feeling is that it is the car, just because it is so random about problems. Yeah the track pad works for the volume and the forward and back for the music. I love it! I can't remember if you have to be on the audio input on the infotainment screen or not. I have just left it on that screen mostly anyway, but I know for a while I was driving with the clock up on the screen and cant remember if I used it then too. I am more likely to do it on the track pad than the steering wheel just cause I am right handed.
52Traction- Yeah I have thought about the USB stick or an always connected music source, but I change what music I am into so often and randomly that I am so used to playing the exact song I want the minute I want it... thanks to being spoiled with a smartphone for so many years. I am fairly sure you can get a ticket for monkeying with your phone at all here too, music or text, GPS etc, but I guess I risk it and frankly I rarely have to touch my phone since I can switch the songs with the steering wheel controls, track pad and use voice command to play whatever song I am looking for with Google Assistant or my music app.
Zarbs- I hardly ever charge my phone in the car. I do so many short trips, 2 miles to work and back 4 times a day and running errands around town, that always plugging the phone in for a 5 min trip would drive me crazy. With Bluetooth, it auto connects, I can either open the app, or if I leave the app open on my phone it just starts playing. Easy (until it disconnects, but this has only happened randomly so far).
