The radio in my trep is acting like it is posessed. Sometimes nothing will work except the letters will be lit, other times the clock will be on with no radio, and other times it works perfectly. If i take it out of the dash and hit it, it generally starts working :bash2: , but id rather now do that all the time. The wires appear snug and all in the harness properly. Is this a bad head unit, or has anyone had this issue before and have a solution?
