So guys, what happend was, i install a aftermarket back up camera to my pioneer avic 5000nex headunit, for the camera power, 12v go to the reverse tail light, and ground go to frame, it was working for couple minute, then when i put the headunit resting on the shift knob, it just turn off, now i got nothing, radio fuse not blown, i even replace the 7.5 multi fuse, what could be the problem?, i check the voltage for the radio 12v, only read less then 1 volt.
