what do you mean remove??. If you want to do so, then I guess start by taking off the molding around the unit (this should be held in by clips) by using a PLASTIC flat head screwdriver (in order not to break the molding). Then continue on by removing the screws that hold your stereo (is it oem?), remove stereo .
If you need more help then comment.
