First Claim
Patent Images
1. A method of updating routing information stored in a mobile positioning device, wherein the routing information corresponds to a predetermined route, comprising:
- dividing the predetermined route into a plurality of segments for delivery as requested by a computer integrated into a vehicle, the total number of segments being determined by dividing the amount of data representing the predetermined route by a number no larger than the amount of memory capacity of the mobile positioning device available for storing the received routing information;
receiving the routing information serially from a server by the computer integrated into a vehicle over a wireless interface established between the server and the computer; and
establishing a communication session between the computer and the mobile positioning device using an interface within the vehicle.

9. An article comprising a machine-readable medium storing instructions for causing data processing apparatus to perform operations comprising:
-
receiving a request for routing information over a wireless communication link from an onboard computer in a vehicle, wherein the routing information comprises a predetermined route and is stored on a server; dividing routing information into portions, such that the size of the portions is a function of an amount of data required to provide a predetermined amount of routing information detail and the memory storage capacity of a positioning device that receives the routing information from the onboard computer; and sending the routing information serially from the server over the wireless communication link to the onboard computer in response to the request. - View Dependent Claims (10, 11, 12)

13. A system for providing routing information to a mobile positioning device, the system comprising:
-
a server storing routing information showing a route in a predetermined amount of detail; and a computer integrated in a transportation means capable of accessing the server wirelessly to exchange routing information with the server, wherein the computer is configured to communicate with a mobile positioning device and to serially deliver routing information to the mobile positioning device in segments determined based, at least in part, on a memory capacity of the mobile positioning device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
