I had the same problem (except leaving me radio in it!!!) on my 1st GTi.
I drilled the backing of the handle and broke it off after I had made several large holes in the handle,
which now seems stupid thanks to the video that spunkymonkey has linked to........Nice 1 by the way

If only I had seen that then, would have saved alot of dicking about with drills and screw drivers!! Doh!
Now on my 2nd GTi, and if it happens again (which it prob will) then ill go the video route!
