Abstract

A navigation system (1) having a navigation system housing (2), which has an internal position-finding unit (9), a data memory (5) and/or a data memory reader unit (6), a display unit (3), an interface (7) to a separate voltage supply source, and a computation and control unit (4) for route guidance and control of the navigation system (1), has locking means (11), which are provided on the navigation system housing (2) for detachable connection of the navigation system housing (2) to a holder (10) which can be mounted in a motor vehicle. The holder (10) has a voltage supply connection (13), which can be connected to the voltage supply system in the motor vehicle, for connection to the interface (7) of the navigation system housing (2). For mobile operation, a separate battery housing (15) is provided, which is designed to hold batteries for the voltage supply for the navigation system (1) and has a voltage supply connection (18), which is provided for connection to the interface (7) on the navigation system housing (2), and has locking means (17) which interact with the locking means (11) on the navigation system housing (2), such that the navigation system (1) can be used in conjunction with the holder (10) as a stationary navigation system (1), and in conjunction with the battery housing (15) as a mobile, portable navigation system (1).

Claims

1. A navigation system (1) having a navigation system housing (2), which has an internal position-finding unit (9), a data memory (5) and/or a data memory reader unit (6), a display unit (3), an interface (7) to a separate voltage supply source, and a computation and control unit (4) for route guidance and control of the navigation system (1), with locking means (11) being provided on the navigation system housing (2) for detachable connection of the navigation system housing (2) to a holder (10) which can be mounted in a motor vehicle, and with the holder (10) having a voltage supply connection (13), which can be connected to the voltage supply system in the motor vehicle, for connection to the interface (7) of the navigation system housing (2), comprising a separate battery housing (15) which is designed to hold batteries for the voltage supply for the navigation system (1) with the battery housing (15) having a voltage supply connection (18), which is provided for connection to the interface (7) of the navigation system housing (2), and having locking means (17) which interact with the locking means (11) on the navigation system housing (2), such that the navigation system (1) can be used in conjunction with the holder (10) as a stationary navigation system (1), and in conjunction with the battery housing (15) as a mobile, portable navigation system (1)

2. The navigation system (1) as claimed in claim 1, wherein the computation and control unit (4) is connected by means of an interface (8), which is arranged on the navigation system housing (2), to an external control unit, and wherein an external control unit (19) is arranged on the battery housing (15) for connection to the interface (8) when the battery housing (15) is locked to the navigation system housing(2)

3. The navigation system (1) as claimed in claim 1, wherein the computation and control unit (4) has an interface (25), which is arranged on the navigation system housing (2), for connection of an external position-finding unit.

4. The navigation system (1) as claimed in claim 3, wherein the computation and control unit (4) is designed for switching the connection of the computation and control unit (4) with the internal position-finding unit (9) to the external position-finding unit when it is found that an external position-finding unit has been connected to the interface (25)

5. The navigation system (1) as claimed in claim 3, wherein the interface (25) for connection of the external position-finding device is a USB (Universal Serial Bus) connection.

6. The navigation system (1) as claimed in claim 1, wherein the computation and control unit (4) is designed to switch the navigation system (1) to a power-saving mode when it is found that the battery housing (15) has been connected to the navigation system housing (2).

7. The navigation system (1) as claimed in claim 6, wherein the power-saving mode comprises the position being determined at longer time intervals with the position-finding device (9) being switched to a standby mode in the time between the position determination processes.

8. The navigation system (1) as claimed in claim 6, wherein the power-saving mode comprises the brightness of the display unit (3) being reduced.

9. The navigation system (1) as claimed in claim 1, wherein the battery housing (15) has a broadcast radio signal antenna (21) which can be connected to the navigation system (1) or has a connection for a broadcast radio signal antenna (21), and the navigations system (1) is designed to evaluate traffic information which is transmitted by broadcast radio and can be received by means of the broadcast radio signal antenna (21) and a receiving unit (24).

10. The navigation system (1) as claimed in claim 1, comprising at least one loudspeaker (26) and/or headset connection which are/is integrated in the navigation system housing (2) and/or the battery housing (15) with the computation and control unit (4) being designed to reproduce video and/or audio signals which can be read from the data memory (5), by the data memory reader unit (6) from a separate data memory (5) and/or can be received by an integrated broadcast radio receiving unit (24).

11. The navigation system (1) as claimed in claim 10, wherein the computation and control unit (4) is designed to read navigation data with the data memory reader unit (6) from a separate data memory (5) and for temporary storage in the internal data memory, and, in addition to the navigation function, the computation and control unit (4) is provided to read audio and/or video data with the data memory reader unit (6) from a separate data memory (5) and for reproduction of the audio and/or video data that has been read.

12. The navigation system (1) as claimed in claim 1, wherein the at least one interface (7, 8, 23) and the locking means (11) are arranged on the navigation system housing (2) in such a way that, when the navigation system housing (2) is locked to the holder (10) or to the battery housing (15), an electrical connection is at the same time made by means of the at least one interface (7, 8, 23) to a corresponding interface connection (13, 14, 18, 20, 22, 24) on the holder (10) or on the battery housing (15)

13. The navigation system (1) as claimed in claim 1, wherein the battery housing (15) has attachment means (27) for detachable connection of the battery housing (15) to a holder (26) which can be fitted permanently.

14. The navigation system (1) as claimed in claim 13, wherein the attachment means (27) is in the form of a Velcro fastener.
