I'm finding that the electronics are VERY buggy in this truck. With the heads up, there were times where I'd set it to the way I wanted in the custom screen, it'd come up on the radio, I'd save it, I'd park the truck for the night and in the morning, it would just show the speed on the windshield. Then I'd have to go through the custom menu again, save it on the radio and hope it'd save until the next morning.
I'm STILL having the troubles with the proximity lighting on both mirrors though. Tonight I went outside to see if it'd work. I unlocked the doors with the key fob, RAM lit up on the ground for an instant, the lights on the mirrors all flashed for the same instant and then they all went out. Radio still goes back to song 1 on the usb everyday too. And I only have 454 miles on my truck.
