I believe you just need a set of special wrenches that go in the slots at the corners of the stock radio... after you pop that, i believe the radio just pulls right out. I am going to try to install it myself... I installed with a buddy of mine my Pioneer AVIC-D2 6" x 4" touch screen GPS navi... it was a pretty stealthy install... the gps and xm antenna were put in the sun roofs track, so you couldn't even tell that i had xm or gps navi systems in the car.
