So is any navigation program designed for phones. The ONLY time a data plan is necessary is in the case where your phone has to connect to download map tiles and/or traffic data. E911 was implemented for a reason, and that reason was safety. They can not disable this service unless they physically shut off the A-GPS device, which is what they have done in the Vogue. Again, navigation programs use the same information that E911 services do, which does not require data.
