The factory stereo installed in the Chevy Colorado only has an AM/FM stereo tuner and a CD player. Many aftermarket stereos, on the other hand, have auxiliary inputs, iPod control and options for setting up Bluetooth wireless. If you want to install an aftermarket stereo in your Chevy Colorado, the first step will be to remove the existing factory stereo. You can do this job with some basic hand tools and a little time.
Items you will need
7-mm socket and ratchet
Eject any CDs that may be in the factory radio. Turn off the ignition of the truck, put it in park and set the parking brake.
