I am the new owner of an IPAD2 Wifi but it is WITHOUT 3G. I did not realize I could not use it as a GPS without 3g, not sure what I was thinking. Anyway people have told me I can get an aftermarket GPS receiver and some have said NO you have to have 3 G so NO GPS without the 3 G so need help. I know I can get the maps on 'net but want the GPS ability. IF I have to will sell this IPAD and get one with 3G or 4G etc. NEED your help!
