GOT MY TRUCK RE-TUNED THE OTHER DAY AFTER DOING SOME WORK TO IT AND NOW MY RADIO WONT COME ON. IT DOES THIS ALMOST EVERY TIME I HAVE IT TUNED BUT USUALLY STARTS WORKING AGAIN 30 MINUTES LATER. ITS BEEN LIKE TWO WEEKS AND ITS STILL NOT WORKING. ITS LIKE ITS NOT GETTING ANY POWER AT ALL (wont turn on,open,or anything). I CHECKED ALL THE FUSES AND ALL THE WIRING, EVEN PULLED IT OUT TO SEE IF ANYTHING MIGHT HAVE CAME UNPLUGGED. ITS A SONY HEAD UNIT. AND THE GUY WHO TUNED IT WAS USING HP TUNING. ANY SUGGESTIONS? HAS THIS EVER HAPPENED TO ANYBODY ELSE?
