2014 FRS Navigation Touch Screen Pioneer
 

I live in Minnesota had my FRS stored for the winter. The other day, the weather was 40° And I took out my FRS. However, the pioneer system was not working right. I lost access to maps, GPS, and radio. The only thing that was working was the CD player.

Does anybody know what happen and is there a reset button that I can push?

thats about 4C and thats pretty warm. So i doubt the cold had anything to do with it. Have you tried trouble shooting? remove and install the battery? maybe unplug and plug the radio's connector? If that doesnt work, it will have to go to toyota for service.
