I just bought a 2002 Tundra SR5 Access cab and want to put my CD Changer in it - it has an FM Radio modulator to run through the factory radio - but i can't figure out how to remove or get access to the radio! I've pulled off the knobs for the A/C, Fan, etc. and took the screws out from behind them, but i still can't remove the black surround piece that covers access to the radio.... anyone know hot to get the old radio out?
