Portable navigation device with wireless interface
First Claim
1. A portable navigation device (PND) comprising:
- a processor;
a graphical display;
memory including map data stored in said memory,user-input device;
signal reception device arranged to receive one or more wireless signals by which a present location of the PND is determined by the processor, in conjunction with user input, desired destination information is determined by the processor, the processor being further capable of performing route calculation and subsequent navigation functions, wherein the location determination, route calculation and navigation functions are performed by software installed on the PND; and
one or more wireless signal transceivers capable of establishing wireless communications with third party devices or systems having corresponding signal transceivers, the software on said PND being adapted to establish a wireless communication with a third party device being a node having a corresponding wireless signal transceiver and being part of a vehicle controller area network including a plurality of nodes, each of said nodes having functionality represented by one or more signals distributed around said controller area network and received by at least said third party device, said PND software further including one or more routines specific to the functionality of one or more of said nodes so as to effectively communicate with said node and utilize its functionality.

Abstract
A portable navigation device (PND) having software adapted to establish a wireless communication with a third party device having a corresponding wireless signal transceiver and which forms one of a plurality of nodes of a vehicle controller area network (CAN). The PND software includes one or more routines specific to the functionality of one or more of said nodes so as to effectively communicate with said node and utilize its functionality. The invention allows the PND, for example, to interrogate the controller area network and retrieve information from one or more nodes on the network for display on the PND or for improved operation thereof, or to cause control or state change of one or more of the nodes.
