there should be 4 square holes on the front of the radio. you need to buy a tool that sticks into those wholes, then you can just pull it out.
if you dont want to buy the tool, you can do what i did and stick 4 nails in the holes and just pull the radio out that way.
hth
Yeah tried that one and cracked my console Dude buy the tools and return them thats what i did (sometime I dont know my own strengh)
