First problem popped up about a week ago. Bought truck one month ago. Radio works fine with key in a/c position. With engine on and running radio screen went to a blank blue color. Even backup camera would not work. Started working then stopped again. Took back to dealer and they said they couldn't work on the hard drives and a re-flash didn't fix it so they ordered a new radio. Waiting,...waiting....waiting for new radio. Anyone else haveing any problems with their brand new 2015's.
