Thus, upon the docking station 420 receiving the navigation device 400 and upon the docking station 420 providing both of a physical connection and an electrical connection, the navigation device 200 may switch from a supply of power from an internal power supply (9 volt for example) to a supply of power from the vehicle (6 volt for example) .

• a positional location at which the navigation device 200 was last connected to a vehicle 400 is stored. Thereafter, upon the navigation system 200 being removed from the vehicle 200, a route to the vehicle can be determined based upon a current location of the navigation device 200 and the stored positional location at which the navigation device 200 was last connected to the vehicle 400. Thus, if the user forgets where his/her car is parked, for example, he/she can easily find the car via the determined route.
• the navigation device 200 may be triggered store the GPS positional location of the navigation device 200 as measured while the navigation device 200 is in the docking device 420. This can occur, for example, upon detecting a connection (physical, electrical, etc.) between the navigation device 200 and the vehicle 400, via docking station 420 for example.

• two kinds of docking may be used, for example: active and passive. Active docking includes a docking station 420 that includes electrical circuits that trigger, in an electrical way, the navigation device 200, when docked, so that the navigation device 200 always knows if it is docked or not by way of an electrical signal.
• Passive docking includes docking the navigation device 200 to the vehicle 400 in a way that does not include any electrical circuits (it may not even include use of a docking station 420). It is just a way to firmly attach the navigation device 200 to the windscreen, dashboard, etc. of a vehicle 400. Still there are ways to detect a docked or undocked state (and thus trigger storage of a last docked location for example) in these passive docking systems as well.
• this can be done, in one example embodiment, by using a "push" sensor that is switched by a mechanical connection of the docking when the navigation device 200 is attached and/or removed.
• the navigation device 200 may be mechanically connected to the vehicle 400, via a passive docking station 420 for example.
• a small switch may be automatically activated by a connection mechanism when the navigation device 200 is connected to a docking station 420, for example.
• "passive" docking can be detected using a magnet, in the docking station 420 for example. Such a magnet can be sensed electrically by a sensor in the navigation device 200, for example.
• a "last docked" position may be stored, in one example embodiment, by: storing the current position as long as the system is "docked” in the docking station 420, for example. In this way, the navigation device 200 does not need to detect any actual connection/ disconnection from the docking station 420, for example. Thus, instead a condition of the vehicle 400 can be detected, indicating a connection between the navigation device 200 and the vehicle 400, wherein the positional location is stored upon detecting the condition. That can be beneficial because, in most cases, the navigation device 200 may be switched off before disconnection from the docking station 420 (and when in a switched- off state, there may be no way to store current position).
• a connected condition is determined, to determine "docked" state via software, i.e. without sensors or mechanical/ electrical switches.
• the software can determine whether the navigation device 200 was used in a different location before.
• This algorithm can use to detect a condition for example, including movement of the vehicle such as speed, for example. Driving with the navigation device 200 occurs at a much higher speed than walking with the navigation device 200, for example.
• the algorithm can use, but is not limited to heuristics to detect a condition for example. This can be done, for example, by detecting that the navigation device 200 has moved more than a certain distance, for example one km before it was switched off. If the navigation device 200 is now switched on again, the location where it was switched off may be stored as a "last docked" location.
• This one km barrier is an example of a barrier which can be used to prevent the navigation device 200 from overriding a "last docked" position with current GPS location.
• an electrical connection between the navigation device and the vehicle 400, via docking station 420 for example may be monitored.
• the positional location of the navigation may be stored as a last docked location and a route can be determined based upon the stored last docked location.
• voltage /current supply from a battery of the vehicle in which the navigation device 200 is docked can be monitored.
• the processor 210 can monitor the voltage /current supply to the navigation device 200. Thereafter, upon detecting a voltage /current supply change upon connection of the navigation device 200 to the docking station in a known manner for example, wherein an automatic switch occurs from a 9 volt internal supply to a 6 volt supply from the battery of the vehicle in which the navigation device 200 is now docked for example, the processor 210 can then request a GPS position signal from antenna/ receiver 250. Upon receiving this position signal, it can then store this "last docked" location in memory 230.
• a "last docked position" may be stored in a memory 230 of the navigation device 220 (and a route can thereafter be determined based upon the stored last docked location).
• a physical connection between the navigation device and the vehicle 400, via docking station 420 for example may be monitored.
