Abstract

Vehicle data generated by circuitry of a vehicle is received and functions of a personal navigation device, which are otherwise used to process device navigational data that are generated by navigational circuitry in the personal navigation device, are used to process the vehicle data to produce output navigational information.

User interlace commands and navigational data are communicated between a personal navigation device and a media head unit of a vehicle, the user interface commands and navigational data being associated with a device user interface of the device, and a vehicle navigation user interface at the media head unit displays navigational information and receives user input for control the display of the navigational information on the media head unit, the vehicle navigation user interface being coordinated with the user interface commands and navigational data associated with the device user interface.
