Head unit reboot after start; tank average fuel mileage reset

I have experienced 2 issues on several occasions:
1) The start-up warning screen on the head unit 'sticks' and eventually (after several miles) it reboots and behaves like normal.
2) The Tank Average Fuel Mileage has reset itself to 0 for no apparent reason. I've experienced this several times.
Neither of these are particularly concerning issues but they are a bit disconcerting.
Has anyone else experienced this?

 

I had the first one happen to me yesterday, sort of. After I got off work I hopped in the truck, started it up and then I heard a weird "chirp" followed by a "click". Then the radio started going haywire. It defaults to play my usb stick music, but it was stuck. The clock came on, but nothing else.

I powered it off, waited, then back on....nothing. After a few more minutes I pulled over, put the truck in park and turned off the engine. I waited 60 seconds then started it back up and everything was back to normal.

Very weird. I have no idea what caused it, but "rebooting" seemed to solve it. Oh, this isn't the first time I've had an odd issue with the radio either. A few months back, the Weather App wouldn't update at all. Another time the Entune Update kept failing.

 

Seems similar, but different. I'll have to have a conversation with my dealer's shop manager about my issues. The only things I utilize the head unit for are radio, navigation & phone ("Pure" phone & text - nothing else). Don't use any other app B/S and am not an audiophile.
