Hope no one else has this happen and it's not a huge deal but today on my 2012 the nav screen wouldn't switch from the globe picture to the hello screen to the regular screen. Called the dealer, he said to re-seat the memory cards. Did that, had no effect, checked the manual, no info there. Started playing with the disp, info and menu buttons to no avail. Just on a hunch, turned on the ignition, held the info button down for about 15 seconds and the nav rebooted and now all is well. Used it two times since, all is well. If this happens again, maybe it'll go back to the dealer, I've heard stories of the 2012 nav re-booting on it's own and having to stop and re-set.
