Hey eviljack, you can copy it, why not, it works awesome!
I had been thinking that would be a good place for the GPS for a while, but the power cord plugs into the back, so it couldn't be a flush mount. I didn't want to drill into the dash either, so I ended up putting a plastic block behind the GPS and using 3M double-sized emblem take to hold it. It seems to hold well, but I just did it today, so I'll have to see how it work over time.
Very nice and clean install! I was going to put some 6 or 7" screens there when I have my system put in, thats a great spot. Lots of space behind the dashboard? Wonder if the space runs all the way across so I can put a monitor on the other side too..
