Method and system for providing backup driving instructions with a navigation system

A method of operation for a navigation services provider that provides navigation-related services to end users' mobile computing devices, the method comprising:

• from the navigation services provider,
• establishing a wireless communications link with an end user's mobile computing device;
• receiving a request from the end user's mobile computing device for directions to travel to a destination;
• sending an initial portion of route guidance data for traveling to the destination to the end user's mobile computing device via the wireless communications link;
• sending subsequent portions of route guidance data for traveling to the destination to the end user's mobile computing device via the wireless communications link as the end user travels toward the destination;
• and
• sending backup driving instruction data to the end user's mobile computing device, said backup driving instruction data capable of providing backup driving instructions without said wireless communication link.

A system for providing route guidance to end users comprising:

• a navigation services provider;
• a wireless communications system connected to the navigation services provider;
• end user computing devices each containing hardware and software for communicating with the navigation services provider over the wireless communications system;
• and
• an application on the navigation services provider that provides dynamic route guidance to each end user computing device for traveling to a destination and backup driving instructions for traveling to the destination in case wireless communications is interrupted and not reestablished.

A method of operation for a navigation services provider that provides navigation-related services to end users' mobile computing devices, the method comprising:

• establishing a wireless communications link between navigation services provider and an end user's mobile computing device;
• receiving a request from the end user's mobile computing device for directions to travel from an origin to a destination;
• sending data for providing dynamic driving instructions for traveling to the destination to the end user's mobile computing device via the wireless communications link;
• and
• sending backup driving instruction data to the end user's mobile computing device, wherein the backup driving instruction data provide instructions for traveling from the origin to the destination, said backup driving instruction data capable of providing backup driving instructions when the dynamic driving instructions data cannot be obtained through the communications link.
