I agree with Tek, it is a butcher job, a Dremel cut is never as good as a cast formed edge
Nytrojen, strange how you were thinking about the swinging, pack-away rotating idea, I was contemplating the same.
Unfortunately for me, it has been many years since I did Machine Dynamics at uni and I struggle to conceptualise the idea before fabricating the curved brackets...that and I don't have a shed to work in with beer anymore so I'm probably doomed from the start.
The worst thng for me was when I was test driving the car, I was totally convinced that the GPS would fit in that cubby hole without cutting away anything, unfortunately the Garmin one I have (it is the same physical size as the one in the Legacy forum but a newer model) is about 4mm too tall once the bracket (with power and swivel holder) is attached and it sticks out about 5mm too far. Seeing as estimate lengths most of the day and am freakishly good at it, I took this as a personal failure
Things get more complicated for me as I use the GPS a lot as it plays MP3s from the onboard SD (HC) card via the built in radio transmitter and I take it out of the Lib every second day to use in my company pool car.
Mind you, I think I can get it to work (i.e find that extra 4mm -ish) if I remove the inner skin of the door and chop the suction part off the swivel mount and mechanically fix it to the rear of the cubby, that way it would still be removable and concealed with the door down. I've got a concealed 12V socket wired under the dash already with power cord so I'd only need to re-run the wire to the cubby (not a big deal)
I'd probably just get a second cubby to return the thing to stock at sale time, cost wise, I'd still be miles ahead if went for a replacement in-dash aftermarket system or Car PC
Now that I'm in North America, I'm greatly concerned about raised pick-up trucks and owners of wedge shaped vehicles. Seriously, not only do you have to be concerned about one hitting you in an accident, they stand a good chance of driving over you at the same time!
