Look for the key shaped tool in the tool bag/box of your car. It is very small in shape and is used to unscrew the stereo. To remove the stereo, browse for the small screws on the dash which is holding the stereo inside the space. Then, unscrew the stereo with the small key shaped tool. But, make sure that you do that carefully not harming the stereo system. Be careful with the wiring as well. The wires connected with the stereo are delicate and while removing the stereo make sure you loosen up all the wires connecting to the stereo.
