Ipad 2 WIFI only as a GPS Navigation

This is a proof of concept . I used a Ipad 2 jailbroken with a 10 dollar TomTom GPS reciever and a 5 dollar app from cydia called BTstack and loaded a Navigon map application downloaded from torrent and found it to work perfectly and was very accurate. Compareded with my Kenwood KVT-512 it was dead on .
