No , I couldn't fix it ... You are the first who reply to this message Will wait , may be other members will give some ideas

2003 IS300 with Metra TYTO-01 harness Did the bypass on my X930BT , moved mute wire straight up/down depends how U looking at it , connected to green parking wire and ground it . Unit starts normal , DVD plays with shifter on D , parking brake not activated , but I cant change/control volume !!! In right upper corner where volume indicator was now only 3 big letters ATT ??? Tried everything , checked connections , wires and so on When I disconnected grounded wires ( green and yellow ) volume control goes back to normal ... could it be that I somehow didn't move the yellow wire
