Maybe this is my problem ,
I connected the mute wire and I'm also using a GMOS-LAN-04 and ASWC Steering wheel button controller, and my unit has been flipping to "MUTE" all but itself and won't release until I shut down completely and re-start.
Seems random but happens a lot, usually after I finish putting everything back together
Taking the day off tomorrow, so I guess I'm taking the radio out yet again. 5th time in 3 days......
