Change the radio in a 1996 gmc jimmy sls?

To change the radio in a 1996 GMC Jimmy SLS, first disconnect the negative battery terminal to avoid any electrical issues. Remove the trim panel surrounding the radio by gently prying it off with a flat tool. Unscrew the mounting screws holding the radio in place, disconnect the wiring harness and antenna cable, then remove the old radio. Install the new radio by reversing the steps: connect the wiring, secure it with screws, and reattach the trim panel before reconnecting the battery.
