Might not be to everyones taste but I bought an ipad 2 3G and made a cheeky holder out of some pine, found 2 old bent radio keys, attached them to the wood and bent into a shape like a 'Z' them so they would slot in under the 'ESP' button and cardholder. Tried to cover it with left over vinyl but had difficulty with wrapping it round the corners so primed it, 6 coats and then sprayed it matte black. Problem with that is that left it in my car down here in france, got a bit too hot and the paint bubbled up like a teenagers face so its back to bare wood for the moment!
I bought the app copilot HD Europe for £44.99 as I was pretty over my garmin old school sat-nav. It is amazing.
I also have xcarlink bluetooth unit so can have all my movies and songs through the stereo
