hi i would like to know if you need 3G or Wifi (offline) to use the Turn by Turn Gps on Garminfone. Is there anything else that needs to be paid? And Anything else I need to know in order to use the Gps function on the garminfone. I dont have the garminfone but im interested so should i get it or is there a better phone with free gps without the need for 3G or wifi (offline)
