GM owns and has owned a lot of different brands over the years, including Chevrolet, GMC, Buick, Pontiac, Hummer and others. Not all GM stereos are the same, but some are easier to remove than others. Take the 2000 Chevrolet Suburban for example. A few clips and five minutes of your time are all that's needed to take out the stock stereo, which leaves you lots of time to install a new one.
Park the car on a flat level surface and push down the parking brake. Tilt the steering column down to its lowest position and put the key in the ignition and turn it to the "on" position. Shift the automatic shift lever to its lowest position.
Grip the dash bezel that goes around the stereo and the gauge cluster and pull it towards you to release the clips. Set the panel to the side then put the gear shifter back in park and turn the key off.
Locate the two plastic tabs on either side of the factory stereo. Push them down using your thumbs and pull the stereo out of the dashboard using your hands. Pull the stereo out and unplug the antenna lead and wiring harness from the back of the stereo.
