I've had the Garmin MC hookup with Jon's dash mount for about a year. My audio plug (male / female) kept coming loose behind the dash. So I cut the cables, removing the little "Y" thing where the power to the gps and audio splits. I had planned on just hooking it direct. I got the power back to the gps but not the audio. Does anyone know how those wires would be configured? I don't know if that little "Y" junction thing needs to be in there or not. TIA.
