Radio Installation

Anybody know where I can find instructions or a diagram of REC navigation install on my commander? How would I go about taking the dashboard apart to change the radio. Thanks in advance.

The front dash cover, or bezel has to come off. On the Commander it runs all the way across the dash. Remove the allen key screws from the front and pulll it off, you will need a new one for the Nav radio. after that its just 4 screws that hold the radio in, two plugs in the back to the harness and the radio antenna cable. Pull the antenna cable by the black plastic piece or you may break it.

Thanks for the help but Do you mean the A/C duct screws and the entire top of the Dash?
