[Accord Man]

it kinda depends on the car and/or install..

you can try inserting a thin piece of something on eacy side, to release the clips.. Most of the time doing it on the side will do..

If not you might need to remove the trim around radio.. If the dude who did the install did it like how I did, it might require removing the entire dash (in a specific order), and undoing the soldering..
