13 button OBC install question

[B-e30_e46]

Do you need to pull the radio? I don't have the special tool to remove the aftermarket head unit the PO installed

its pretty hard to do w/o doing that... you have to get your hand in behind it... someone else help me out with this...

you dont HAVE to pull the radio, but it will be 94857392847 times easier if you do. usually you can just use something thin and flat and long to pry out the sides, but get the special tool and do it right, you can probably buy the special tool from crutchfield.com or im sure any stereo shop can get it for you.
