Went on an errand today so I had 2 successful starts without my phone trying native AA to the Uconnect before Carplay has had a chance to start up. It took a little while but Carplay connected. My wireless AA actually connects to the AI box first before Carplay start on the display. Apparently the box is visible as an AA client even if not displaying on the Uconnect screen as carplay.
Which brings me to an annoyance: The data port USB's stay powered (hot) for about 1hr after the truck is turned off. So at home, my phone keeps randomly reconnecting to wireless AA to the AI box and starts streaming music to nowhere. So its fine if you are going to a store, work, restaurant, but once you get home you need to pull power from the AI box. A little annoying but not a showstopper.
No failures, no random "restart to screen calibration" today. I think what caused that was me tinkering around adding carplay home screens which are different size than full screen carplay. Also testing in my Mach E changed the resolution again. I think it is now good and remembers the full portrait aspect without rebooting itself.
Is that enough for the next person to order one? Could use a small group for when we find issues and come up with workarounds. It was $69 on Amazon after the $20 coupon.
