i dont know if you have a GTI or not, but the MkV GTI has a little shelf in the glove compartment to hold the owner's manual. i just cut that shelf out, and made two pieces of metal that fit the opening to cover the gaps on either side of the head unit. its held in place behind the glove compartment by bolting the head unit to a heavy wire mesh that is fiberglassed to the side of the shelf. its a little hard to describe, and i don't have any pics of the progress. needless to say, it just took some creative thinking. it aint pretty behind the head unit, but it works and it is really secure.
