any Info in installing an avic d3 in a Pontiac grand prix 2004 gtp wit monsoon system. I will be using a GMOS-04 harness. Any info will be apreciate it. Ex what wires are what colors. Vss, reverse any thing .

The module will give you all the wiring you need, except on those vehicles the factory radio needs to be relocated to the trunk to retain the full functionality of the seperate display on the dash.

Reloacte the factory headunit to the trunk running just power, ground, green data wires and a purple wire.
