7.85" iPad makes a perfect take along GPS, with additional functionality. Many car gps screens are 7" already so this is only marginally bigger. I currently have a Samsung galaxy 7 plus which I use for this purpose. Nice thing about it is that when it's time to get out of the car, I unmount it and put it in my sons backpack and let him use it throughout the day to watch movies and play games. I actually like the Samsung, however, android is a bit too buggy for my liking. I own 2 iPads MacBook air, 2 iPhones, 2 appletv's and a macmini. I love my apple stuff, and a 7" iPad would keep me fully connected...
