I am looking at using my Ipad Mini as a car GPS as my Garmin has seen its better days. I preordered the Mini with Verizon LTE. I already bought Navigon for my iPad 3 but it is just too big for in car and my iphone 4S is just too small for my needs. 1st - Does this seem like a viable option? 2nd - Are there any companies that make a dash mount somewhat like my Garmin has?
