You need the radio "keys" that can be purchased from the dealer for only a few bucks!

THey are 2 little metal key-type peices that slip into those 2 lower slots of the stereo... once in, you can then pull out the radio.

Also, there will be no need to remove anything else... they radio can be removed independently.

Good luck!
