This morning I fired up the Rover and it started (-8 on the temp sensor) but the GPS display did not come on. I drove for about an hour, reached my first stop, shut it down for about a minute. I then restarted, and still no GPS display, I then noticed I had no volume control either. I drove for about 35 more minutes and then parked for about 10 minutes. When I came back out I started the truck and everything was working again. Has this ever happened to any one?

 

At that temperature i'd say the screen was just slow to operate. Most screens aren't made to operate in low temperatures and slow significantly as they approach the point of not working period. I've had it happen in another vehicle before but my newer Rover hasn't run into cold enough temperatures for that to happen!
