Has anybody removed the gray(or brown or whatever color your interior is)dash panel that surrounds the radio, HVAC controls, goes all the way over the steering column and covers the power mirror controls, etc. How hard or easy is this? Does it just snap on or is it held in place with screws? I tried just popping it off w/a screwdriver today and had no luck, it seemed quite solid and I didn't want to break anything. I need to remove it in order to install a custom mounting bracket for my XM Skyfi. Please help.
