How do i remove the factory radio on my 1983 cadillac fleetwood
Locate and remove two (2) phillips screws that secure the top of the plastic panel that surrounds the radio. The plastic dash panel will pull off once the screws are removed as shown in the photo above.
The front of the radio is held in with two (2) 7mm bolt screws at the top of the radio. Remove the 2 bolt screws.
There is a hidden radio that secures the rear of the radio and is located under the radio. Pull the ashtray to its extended position. You will need to lay on your back or side and look behind the ashtray, up to the bottom of the radio.
Once the ashtray has been pull to its extended position, you should be able to locate and remove one (1) 7mm bolt screw as seen in the photo above.
Once all screws have been removed, the radio can then be removed. Pull firmly on the radio to remove it from the dash. The radio will most likely resist pulling from the dash. The antenna cable which plugs into the rear of the radio is very short and gives the radio resistance when trying to pull the radio out of the dash. Continue to pull firmly and the antenna cable will unplug itself as the radio is pulled from the dash.
Unplug (1) blue, (1) white, and (1) black wire harness connector(s) from the rear of the radio. There will also be wires extending from the rear of the radio with a plastic connector attached to the wires about 4 inches from the rear of the radio. Unplug this small connector. The radio can now be completely removed from the dash. Set it aside. You will need to remove the plastic brackets attached to the top and bottom of the GM radio. This will be shown in detail in the "Mount New Radio" section.
Hope these helps....
