Wow. So sorry for what you have experienced. It is reports like this that make me nervous considering taking my GT for long trips. I was planning on driving my daughter up to college later this week but knowing some of these issues now makes me think of taking our "reliable" ICE vehicle instead. I have had some screen drop outs recently as well and have noticed it always happens after trying to use TIDAL and then TIDAL freezes. Not sure if it is a coincidence. Certainly is annoying not to be able to use any functions on the right screen or pilot panel unless stopping to reset the car. If it weren't for the amazing driving experience, I am sure a lot of us would be unloading these cars. This is my daily driver and having these type of glitches is very concerning.
I drove my family all the way from Millbrae, CA to Denver visiting 4 National Parks. Then continued home to Indy by myself. I have a thread on this forum dedicated to that trip.
We crossed the California, Nevada, Utah and New Mexico deserts in June with temps over 100°. Death Valley was 120° after that I wasn't worried we'd get stranded.
You will be fine.
TIDAL implementation is not good. I'm not sure but when the platform first came out there were issues with many players being unable or having difficulty unfolding MQA. There mere fact it cannot continue from where it left off, playlist or album, I wonder if it's the car or TIDAL.
This alone should be enough to allow hardwire connection!!!
