i use tomtom7 on mine.. with any data reliant gps software, you lose the ability to talk on the phone while using it, and i normally use gps while in nyc so i don't have to read street numbers (my eyes are terrible at night), and i'm normally on the phone. sprint nav really isn't that bad though, i've been using it for years on other phones. but given the choice, i would most certainly choose tomtom7. though, i use sprint nav for traffic reports, because its pretty damn acurate.
