Let me get free and hopefully will do it on this weekend. I've got some ideas.
You seem to have read my mind. Personally, I'd prefer a dockable iPad Mini 2 (Wi-Fi+Cellular) or use my iPhone for navigation purpose. There are so many after market options out there, you really don't need to spend that insane amount on a crappy unit costing 75,000 or more.
Yes, very much.
As per my view point, there is a limited set of wheels which you could say strike a balance between sports oriented cool and conservative or decent. It has to be either way. Wheels may be the last addition. But lets wait and see.
