Navigation / Radio Random Restart Fixes

OK... My truck did it twice yesterday and 3 times today during a trip up north and back home.... I was listening to the USB music... no phone connection.... It rebooted and came up with the "maintenance required" bullshit...I just told it to play my USB music and it did... No rain or other shit...

I think it just needs a slap across the side of the head unit..!! Or maybe a software upgrade..??
Can I do this myself or is another thing that I have to see the freakin' dealer about...??

 

My 2014 has been doing it off an on for several years. I never bothered to have it documented at the Dealer. Now the system will not pair with any cellphone or other bluetooth device. I can hardly wait to see what this will cost.

 

This issue continued to the point where I lost all Bluetooth capability and the Bluetooth settings disappeared from the setup screen.
I found another thread about the Bluetooth issue and someone posted the following link for an Entune software update and it seems to have resolved the issue...
