hey guys does anybody have or know where I can find the vehicle schematic for the above mentioned GS? It also has the ML audio w/ navi. running into a few interior electrical problems and ive checked all fuses, which leads me to believe its beyond the fuses. If anybody is interested in the issues the following are occurring: no dome lights work, key remote does not work (new battery), also on a side note, navigation dvd will not eject, and cd changer will not eject, and I get the "audio off" message on the screen. It appears the previous owner might've had an alarm with remote start installed and then was removed prior to selling, and im thinking maybe upon removal they might've jacked something up on the inside. Any and all help is appreciated. thanks guys.
