This was a perfect fit in my 2005 trailblazer. I can't beleive how much better this is than the stock stereo. It's in a totally different class, it's awsome. The installation package from crutchfield made this extremely easy to install. The wiring harness matched perfectly with the stereo's harness.
Great price. Easy install. Great sound
I can't think of any it's exactly what I wanted
