Abstract

A navigation system for vehicles, including a navigation device and a unit for determination of positional data connected to the navigation device for determining the actual position of the vehicle and for transmitting this positional data to the navigation device. By utilizing a communication interface, the navigation device is capable of establishing a communication between the navigation device and a hands-free control unit for cellular phones for installation in a vehicle and for transmitting audio signals from the navigation device through the hands-free control unit to audio output means, which are connectable to the hands-free control unit.

Claims

1. A navigation system for vehicles comprising:

a navigation device;

a unit for determining positional data connected to the navigation device, the unit for determining actual position of the vehicle and for transmitting said positional data to the navigation device;

a hands-free control unit for cellular phones;

means for providing an audio output connectable to the hands-free control unit; and

a communication interface for establishing a communication between said navigation device and the hands-free control unit, wherein the communication interface transmits audio signals from the navigation device through the hands-free control unit to the means for providing an audio output.

2. The navigation system in accordance with claim 1, wherein said communication interface includes:

a holding device for holding the cellular phone; and

an adaptor plug attachable between the hands-free control unit and the holding device such that said navigation system and said cellular phone can use an audio signal input of said hands free control unit.

3. The navigation system in accordance with claim 1, wherein said navigation device is equipped with a power supply interface connectable with the hands-free control unit to supply said navigation system with service voltage.

4. The navigation system in accordance with claim 3, wherein the power supply interface comprises the adaptor plug which is attached between the hands-free control unit and the holding device, the adaptor plug establishing a first connection to the power supply of the hands free control unit at one end, and a second connection for simultaneously providing service voltage to the navigation system and the cellular phone over the hands-free control unit.

5. The navigation system in accordance with claim 3, wherein said communication interface and said power supply interface comprise one adaptor plug.

6. The navigation system in accordance with claim 2, wherein said adaptor plug has a connection to a power supply source and provides a service voltage to the navigation system over said connection and wherein the service voltage of the cellular phone is separately provided from the hands-free control unit over the adaptor plug.

7. The navigation system in accordance with claim 1, wherein said communication interface is designed to exchange signalling data and/or control data between the cellular phone and the navigation device.

8. The navigation system in accordance with claim 7, wherein said navigation device is equipped with display means and said navigation device is designed to display the signalling data of the cellular phone on said display means.

9. The navigation system in accordance with claim 7, wherein the navigation device is capable of converting the control data from the cellular phone.

10. The navigation system in accordance claim 1, wherein the communication interface is equipped with a signal converter which converts the audio signals of the navigation device such that the hands-free control unit recognizes said audio signals as audio signals of the cellular phone.

11. The navigation system in accordance with claim 10, wherein the navigation device is capable of generating and sending an activation signal of the cellular phone over the communication interface to the hands-free control unit when said navigation device is activated.

12. The navigation system in accordance with claim 1, wherein the navigation device is capable of generating and sending a radio mute signal over the communication interface to the hands-free control unit when the audio signals are transmitted from said navigation system to the hands-free control unit.

13. The navigation system in accordance with claim 2, wherein the communication interface is as a wireless link.

14. The navigation system in accordance to claim 13, wherein the wireless link is designed to communicate with the cellular phone, the holding device for the cellular phone, the adaptor plug, or the hands-free control unit.

15. The navigation system in accordance with claim 1, wherein the unit for determining positional data is a satellite positioning unit.

16. The navigation system in accordance with claim 1, wherein the unit for determining positional data is the cellular phone and the communication interface is designed to transmit the positional data from the cellular phone to the navigation device.

17. The navigation system in accordance with claim 7, further comprising a microphone, wherein the navigation device is designed to analyze and to achieve speech commands which are inputted over the microphone, wherein said speech commands represent the control data.

18. The navigation system in accordance with claim 1, wherein said navigation system further comprises means for reading memory devices, said navigation system designed to read the audio signals from said memory devices and to transmit said audio signals over the hands-free control unit through the audio output means, said audio output means connected to said hands-free control unit.
