its easy to trim out. simply pull it off. the simplest way to do it is to put your thumb in the cig lighter and just simply pull. now once that comes off your going to have to unhook your hazard lights, and your trac control. this is easy as well. for the hazards you'll need a small flat head. one those are unhooked move the piece to the side. you'll need to move the gear selector out of park. pull up on the parking brake, turn the key to on, and move the lever to drive or lower.once the trim piece is out of the way, then you'll see 3 screws. there either 7 or 8mm. i'm pretty sure there 7, but i'm not 100%. take out those screws and pull the radio out. there are then 2 conectors on the back of the radio. one is the antenna, the other is is all the electrical and everything. take those out, and the radio comes right out.
oh one last thing, when you pull the trim off, the plastic trim piece around the key is going to come off. thats normal, and it will pop back in. just make sure you catch it, or see where ti goes.
i've pulled out my radio about 15 times, its really not hard.
good luck
