    David, there are plenty of car stereos that you can use in your 2005 Chevrolet Colorado. We recommend:

    Pioneer DEH-1300MP MP3 Car Stereo

    The car radio features a front panel auxiliary input for your MP3 player and the ability to read MP3 CD’s. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2005 Chevrolet Colorado car stereo installation.
