I'm new here, so I want to say Hi! and then ask a question. After about 45 minutes to an hour of use, plugged into to my 12 volt outlet in my pickup my 730 that scrolls through screen after screen over and over again. I have deleted the program and reinstalled 6 or 7 times and it still happens. If I leave it off for a couple of hours it runs ok for another 30 minutes to an hour. Anyone have any ideas about how to fix this problem?
