orestovich Posted May 28, 2011 Report Share Posted May 28, 2011 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 right ? May be its not all the way in in the connector harness ? Don't know what to do , any help would be appreciated Quote Link to post Share on other sites

Sir Bob TreeWhale Posted August 1, 2011 Report Share Posted August 1, 2011 ATT means mute, so I don't think you did the bypass right... Quote Link to post Share on other sites
drkhead Posted September 9, 2011 Report Share Posted September 9, 2011 FYI - ATT stands for attenuated... Quote Link to post Share on other sites

That SCREAMS "you didn't do the bypass right" it's the yellow wire causing it and it's most likely in the wrong location. That answers you too coachzenn Quote Link to post Share on other sites
