The Buick Century as produced by General Motors came equipped with an in-dash stereo. Owners who want to upgrade the stereo system by buying and installing an aftermarket stereo must remove this existing factory radio before they can undertake the improvement. While some disassembly of the dash is required, it’s not a complicated procedure.
Step 1 – Set the parking brake for the car, and use your adjustable wrench to remove the negative cable from the battery.
Step 2 – Loosen and remove two 9/32-inch screws located below the housing holding the climate controls. Pull the housing off and remove.
Step 3 – Pry off a round plastic clip on the left side of the knee panel (underneath the steering wheel) with your panel tool. Remove a 9/32-inch screw from the right side of the knee panel and remove the knee panel.
