i have researched the wifi only ipads using a mobile hotspot and driving around using the navigation app...
basic answer is it wont work that way.
ways it will work, if you have an cellular enabled ipad and pay for the data service like through verizon or att. That works perfect
or if you already have or buy a cellular enabled ipad WITHOUT the data service activated. Then have a mobile hotspot, then the navigation apps with work.
The wifi only ipads dont have the GPS chip/antenna in them.
so like the post above you can get a external GPS modular, a wifi only ipad, and a mobile hotspot and that will work.
so after all the different scenarios and some math...
i want an ipad mini. so it would be more cost effective to purchase a new ipad mini with 4g service and add it to my current verizon plan.
but say you already have a ipad or ipad mini wifi only.. it prob be cheaper to buy the external GPS modular and get a mobile hotspot
the mobile hotspots are fairly cheap unit and 20 bucks a month add on to existing plan (verizon)
vs buying a 16 gig ipad mini 4G LTE is lots of monies, but its only 10 bucks a month to add to existing plan (verizon)
so xmas gift to my self = ipad mini
