I use a Ram Mount RAM-A-CAN and Tab-Tite setup for my iPad ( Apple iPad Holders & Mounts ):

My only complaint lies with the quality of the Land Rover cupholders being a bit loose and wobbly, so therefore the iPad wobbles too!
But I do like the low position of the iPad, in that it doesn't block any of my view out of the front window and the holder is easily removable when not required or being used.
