Abstract
A navigational aid including an intelligent display mode and a communication system communicates with a vehicle'"'"'s sensor system and/or historical- or time-based information to reduce the number of businesses that are displayed on the map by filtering out unneeded or less preferred services. When the vehicle'"'"'s fuel level sensor detects that the fuel tank is almost empty, a message can be sent from the sensor system to the navigational aid such that the navigational aid can then begin showing a visual indication (e.g., text or graphical information such as an icon) of the location of fuel stations on the screen. Additionally, the location receiver indicates to the filter when the navigational aid is close to the programmed destination. At that point, the filter can be informed that it should start showing garages or areas where the vehicle can be parked without having cluttered the screen with parking garages that were not close to the destination. Similarly, when in need of other services (e.g., hotel or restaurant services), the navigational aid can display preferred brands (while omitting non-preferred brands) and make reservations when a communication system is included which is capable of communicating with the service provider. Additionally, prices or relative prices for the services may also be indicated.
