I installed the GM12-AUXV2 unit yesterday. The upper dash cover removal was just as much fun as others stated it would be....
I ended up using the power from the cigarette lighter. I cut the power leads to the lighter after the GM power plug and I then added my own two wire connector. This lets me reconnect the cigarette lighter if I decided to at a later time. (That's not going to happen).
I had to make one internal dash modification. The GM12-AUXV2 plugs into the passenger side rear of the radio head unit. When you attempt to slide the radio head unit back into place, the wire connector for the GM12-AUXV2 hits the plastic of the dash enclosure directly behind it. The other side of the radio head unit has a lower lip in the dash enclosure and that is how the GM connector avoids the issue. I ended up cutting out a small chunk of the dash enclosure directly behind where the GM12-AUXV2 plugs into the radio head unit.
I then mounted the GM12-AUXV2 electronics module on the back/right side of the ash tray drop panel. This way all I have to do to connect my MP3 player is open the ash tray compartment and pull out the connecting wire that I store in the ash tray and connect it to my mp3 player.
The first picture is the GM12-AUXV2 plug on the back side of the radio head unit. The second picture shows the GM12-AUXV2 unit in the ash tray compartment.
