I installed this stereo in my '02 trailblazer and it fit perfectly! Overall I really like it, but there is something that bugs me. If you are playing music from an SD card and shut your car off, when you turn it back on the radio seems to always goes back to the first song on the SD card. Other than that I really like it and am very glad I got it. I would suggest completely reading the manual as there are a number of features I did not know about until after I read it a week after I installed it. I would give it all five stars but a piece of equipment like this does have delicate parts and it can be hard to operate while driving.
