Attention: 
1. The radio is a snap to install in your GMC.  Simply remove the plastic bezel surrounding the radio, unscrew the factory radio, and screw this one in its place.  The factory wiring harness plugs into the new radio's harness, and it comes with an external speaker that you plug in and leave behind the dash for the turn signals and warning beeps and sounds.  (Note, some customers think that the speaker is too loud.  To quiet the sound, use tape to cover most of the speaker.)
2. The original On-Star system will be invalid after installing this head unit.
3. This radio is not compatible with the factory backup camera, please install an aftermarket backup camera instead.
4. If your car equips with a roof monitor, then it will not display DVD video after installing this radio.
5. This product only fits vehicles that come with the left radio as shown in the below photo. Please DO NOT buy if your vehicle has the right radio as shown in the below photo.
