I have a 05 srt6 with the Infinity NAV radio and the screen fades from the heat. When I get in the car I can barely read anything on the screen but after 15 mins or so of running the A/C on high I can start to see the screen again. By the time i get home from work, hour plus drive , its almost normal. Has anyone had this problem before? I tried searching but I couldn't find anything. If someone has had this issue is there a fix beside swapping out the radio?
