something odd has been happening with my headunit. its a pioneer, its a good headunit, and i know its wired properly. heres the situation, the headunit has power, but wont play any music, then say after driving for about 10-15 minutes the music will start playing. the weird thing about this problem is that it usually only happens on days that it is COLD outside, odd i know. it doesnt happen everyday, usually just days its cold. any ideas?
