If the radio is DIN mounted (meaning slid into a metal sleeve inside of a dash kit), then the trim ring should come off by unhooking the top and bottom edges, then you should see the clasps on the sides of the radio, slide them up to center as you pull slightly on the radio. Once the radio starts to slide out take care and not rip the whole thing in one shot, wiring harnesses, antennas, and RCAs may be tangled up. Good luck
