From memory I think its actually a little shallower.
If my garage wasn't such a f*cking mess I'd probably be able to find the one I took out when I got shot of the car, and I'd send it to you for nowt. However, it's too cold for cleaning out the garage now!
From memory I think the pocket was about £18 from the dealership, although the parts guy gave me one that came out of a showroom polo (was having an autochanger retro-fitted IIRC)
