So today I had Will Google how to "reboot" the main screen and the driver screen. Holding the top right and left buttons on the steering wheel reboots the drivers console. Holding the right and left scroll buttons on the steering wheel reboots the main center screen. I of course pulled over to do this but am pretty sure it does not affect the main systems (have seen both reboot on their own while driving before).
It seems to have solved the problems with the audio system and with the Nav system. Problem solved!
