I'm thinking about buying a A/V Receiver called AVH-P4200DVD (Which has a 7in" screen.) Is there any kits out there that could replace the old audio dash to fit this size screen?
no double din will work in your truck 99-02 trucks have a smaller area for the radio in the dash what you can do is get the dash bezel from an 03+ truck and move your ac controls down a bit its not really hard heres a write up on how to do it.
Go to this web link, scroll down to "Please select your car"...... i also have an 01 Sierra with ext. cab, 4 door with onstar and they dont make a kit for it..... good luck....
