On each side of the radio, grasp the vertical trim pieces on each side and they will slide off (pull to you). There are some pressure pins that hold them on, but they come off very easily. Behind those trim pieces there are some screws to remove. There are holes for 3 screws on each side but mine only had one phillips screw in each side. Once the screws are out...simply slide the radio unit out to you. There was a lot of wire behind the unit, so you should not damage anything.
