I have a 2000 gmc sonoma with a factory cd,am-fm . The owners manual says this unit could be equiped with optional cd changer. And it has a button labeled ” cd/aux”. My question is, is there a factory hookup wiring for the optional cd changer that can be used to hook up a mp3 player( I-pod ) somewhere already in the truck?
i have a 1991 gmc sonoma 2wd and i just want to know how do i take off the door pannel to get ot the speakers
wiring diagram for 1991 sonoma gmc pickup
Miquan, most door panel removals can be done with a Phillips screwdriver and by simply pulling the door panel off by hand. Just look for screws at the edge of the door panel, near the door handle or inside the door pull. Once you remove all the screws or plastic tabs, you should be able to pull the door panel off with ease by lifting up and out. Hope this helps. Good luck with your 1991 GMC Sonoma door panel removal.
