do you still have the standard stereo?
if you do... then get the B2 mount, and simply slide it in the gap between the bottom of the stereo and the silver surround.
It slots in there perfectly, and is nice and easy to remove and looks smart too.
If you dont have the standard stereo, then i dont know cos i havent used mine since changing stereos, mainly cos i had nowhere to put the thing
Im gonna stop talking now
cheers, Dan.
