Navigation system and methods for route navigation

摘要

Embodiments of the present invention include systems and methods for improved navigation using the global positioning system (GPS). A method of improved navigation includes transmitting a destination to a navigation server through a wireless communication channel. The method further includes transmitting position information from a GPS-enabled device to the navigation server through the wireless communication channel automatically at a time interval. The method further includes generating navigation information by the navigation server. The navigation information is based on the position information and the destination. The method further includes receiving navigation information on the GPS-enabled device from the navigation server through the wireless communication channel.

主权项

1. A method of providing improved navigation using a contact list stored on a mobile device, the method comprising:
at a GPS-enabled car navigation system communicatively coupled to the mobile device via a communication link, receiving the contact list comprising a set of contacts from the mobile device via the communication link, each particular contact comprising an identity and a physical address of the particular contact; at the car navigation system, receiving an identity of a contact from the received set of contacts; at the car navigation system, mapping the identity of the contact to a physical address of the contact, wherein the physical address is received from the mobile device; and at the car navigation system, determining navigation information based on a current location as a starting point and the physical address of the contact as a destination without communicating with the mobile device.
