you mean something like this.
Mind you, as you can see from the 3rd photo, it's all been changes a bit since. The GPS receiver is now stuck under the sunroof, the netbook is a slightly larger one, and the bracket that you see with the "sucker" on in photo 2 that was never sturdy enough, has been cut about and attached to a piece of metal etc to bring the whole netbook down & forward so now it's at an angle just in front of the heater vents.
