I purchased a WiFi only mini iPad 2 to use with my P3 for when it finally arrives. I was wondering how you cash your maps at a new location with a WiFi only tablet? Do you have to link it to your cell phone hotspot? If so after you have cashed the map can you unlink it and still have the maps and gps work in the app? Do you want to keep WiFi on or turn it off? Thanks for any help.
