A vehicle-based system can communicate with a personal navigation device, to pass both automatic instructions and driver instructions to the personal navigation device. Using information and instructions passed from the vehicle-based system, the navigation device can be controlled to, among other things, provide directions, provide vehicle status warnings, and navigate without a GPS signal. Output from the personal navigation device can be delivered to the vehicle based system for playback through, for example, vehicle speakers. |
