Swapped with my other Envoy aftermarket headunit with aftermarket harness adapter(works in other). Turns on but no sound. What could be the problem.
its doubtful both head units are faulty.
most likely a bad wire in the aftermarket harness.
you need to double check all connections.
what model harness is it?
Not aftermarket issue.
Works fine in my other Envoy.
What I am.having is no sound out of either the Factory of the aftermarket units.
The factory units display wouldn't light up,
No sound from it or chime.
When the aftermarket was installed turns on fine but same thing No sound or chime.
Took everything out and replugged everything like from scratch. Still no sound.
