AmazeGPS is still free... BUt the shiznit will be: Google official navigator(not the hack one that sucks imho) that is coming soon for WM(already out for droid) and will be free as well. It has most complete package of features that are not found on any current GPS. It will come with TTS, turn by turn, Traffic, Search by (natural)Voice with google assist(like say go to nearest movie theater with closest Titanic start time), Sattelite View and Street view(photo quality same as on GM) and others, will pwn all other GPS soft/PNA's free and paid
!!! Most exciting GPS soft and i have GarminXT, TomTom(PNA and PDA), iGO8, AmazeGPS, Waze and build in MB one(will most likely unistall/turn off all once GN is out for WM and stable enough)!
