The Chevrolet Impala came with a few different stereo options in 2005, but back then, no one knew what would be available in the future. Today's vehicles can come with navigation, satellite radio or a plug for your MP3 player, and even more options, depending on what you're looking for. You can buy a stereo with all of these features, and if you install it in your '05 Impala, you can add the features to the car and maybe even raise the resale value in the process.
Remove the two phillips-head screws on either side of the dash trim bezel using the phillips-head screwdriver. Place the nylon pry bar between the trim bezel and the surrounding dashboard, then tilt the pry bar back to pop the panel off of the dash. Remove the two phillips-head screws underneath the gauge cluster using the phillips-head screwdriver.
Pull off the trim panel below the steering column using your hands. Unscrew the two screws in the knee panel using the phillips-head screwdriver. Unclip the knee panel from the dash using your hands. Remove the single screw to the right of the steering column using the phillips-head screwdriver. Pull off the entire dash bezel from the dashboard. Unbolt the stereo from the dashboard using the 1/4-inch ratchet and socket, then slide it out of the dashboard and unplug all connections to the stereo. Leave these connections hanging out of the dashboard.
Install the vehicle-specific dash kit into the dashboard using the 1/4-inch ratchet and socket. Take the cage from the aftermarket stereo and put it inside of the dash kit. Secure it to the kit using the flathead screwdriver. Use the wire strippers to remove the end of the wires on the wiring harness that came with the new stereo as well as the vehicle-specific wiring harness. Match up the colors on the two harnesses. Crimp the matching colors together using the wire crimpers and the blue butt connectors.
Plug in the end of the harness you just made in Step 3 onto the harness hanging out of the dashboard. Plug the other end into the back of the replacement stereo. Plug the antenna lead into the back of the replacement stereo. Mount the stereo inside the cage. Reassemble the dashboard in the reverse order of disassembly.
