I'm trying to install my a motorola bluetooth kit in a 2003 GX470 with Navigation and Mark Levinson.  I'm looking for the basic wires:

Acc power
Power
Mute
Speaker wires

I search the forum and saw a post for a 2006 standard stereo, but I don't think its the same as the stereo that is integrated in with the nav screen.   If anyone has this information, please let me know!

Thanks in advance,
Will
