On June 18, 2009, the US Patent & Trademark Office published a patent application from Apple that reveals one of the next chapters for Apple's iPhone navigation systems and services.   Implementations of the invention can realize one or more of the following advantages. The driver of a vehicle can be provided real-time information related to the operational state of the vehicle (e.g., the level of fuel in the vehicle). In some implementations, the driver is automatically provided advance warning of a refueling location and information about where the vehicle can conveniently be refueled. In other implementations, the driver is provided notification of a vehicle maintenance issue and given immediate information about conveniently located vehicle repair stations. These features can reduce driver distraction, reduce the risk of the vehicle running out of fuel and thereby improve road safety for the driver. The system also introduces the concept of filtering the information streamed to you. For instance, you may drive a Mercedes-Benz or other high end vehicle and so for repairs on the road, the system will only point out service stations for that model. The filter also allows users to choose their favorite gas stations, a required fuel type or even the types of restaurants you want to eat at while filling up. On the road, and only on the road, I look for Denny's Restaurants - and so having them pointed out to me on this navigational system would help me plan a better trip.  And lastly, the patent indirectly points to the navigational system being able to pick up television signals.
