3. The rearview mirror assembly of claim 1, wherein at least one of said first and second microphone subassemblies comprises more than one transducer.

4. The rearview mirror assembly of claim 1, wherein at least one of said first and second microphone subassemblies comprises more than one microphone.

5. A vehicle rearview assembly for providing an image of a scene to the rear of the driver of the vehicle, said rearview assembly comprising:

a mounting structure for mounting to the vehicle;

an audio/data transceiver for transmitting and receiving audio and data signals to/from a portable telephone;

a hands-free microphone associated with said mounting structure for providing an audio signal to said audio/data transceiver; and

a control circuit coupled to said audio/data transceiver, said control circuit determines whether a portable telephone having a predetermined identification code is within the range of said audio/data transceiver and exchanges data with the portable telephone through said audio/data transceiver causing the portable telephone to disable its microphone, wherein said control circuit enables speech to be picked up by said hands-free microphone and transmitted to the portable telephone through said audio/data transceiver.

6. The vehicle rearview assembly of claim 5, wherein said control circuit exchanges data with the portable telephone through the audio/data transceiver to enable audio signals from called/calling party that are received through the portable telephone to be transmitted through said audio/data transceiver and played back over a speaker of the vehicle.

7. The vehicle rearview assembly of claim 6, wherein said control circuit exchanges data with the portable telephone through the audio and data transceiver causing the portable telephone to disable its speaker.

8. The vehicle rearview assembly of claim 5, wherein, during a telephone call through the portable telephone, said control circuit selectively enables said hands-free microphone when the portable telephone is within range of said audio/data transceiver.

9. The vehicle rearview assembly of claim 8 and further including a call transfer switch coupled to said control circuit, wherein said control circuit enables said hands-free microphone in response to an activation of said call transfer switch.

10. The vehicle rearview assembly of claim 8, wherein, during a telephone call through the portable telephone, said control circuit enables said hands-free microphone and disables the microphone of the portable telephone as soon as said control circuit detects that the vehicle is moving.

11. The vehicle rearview assembly of claim 8, wherein, during a telephone call through the portable telephone, said control circuit enables said hands-free microphone as soon as said control circuit detects that a person using the portable telephone is within the vehicle.

12. The vehicle rearview assembly of claim 5, wherein said control circuit is configured to exchange data with more than one portable telephone through said audio/data transceiver.

13. A rearview assembly for a vehicle comprising:

a housing for attachment to the vehicle;

a display positioned in said housing;

an audio/data transceiver associated with said housing for receiving wireless audio and data signals from a device proximate the vehicle; and

a controller positioned in said housing and coupled to said display and said audio/data transceiver, said controller controls said display to indicate the presence of a wireless connection to a device proximate the vehicle.

14. The rearview assembly of claim 13, wherein said display is configured to display the identity of the device to which a wireless connection is made.

15. The rearview assembly of claim 13 and further comprising a hands-free microphone associated with said mounting structure for providing an audio signal to said audio/data transceiver.

16. The rearview assembly of claim 15, wherein said controller determines whether portable telephones having predetermined identification codes are within the range of said audio/data transceiver, said control circuit being configured to establish a priority amongst the portable telephones for use of said hands-free microphone and said hands-free speakers, said controller exchanges data with the portable telephones through said audio/data transceiver causing the portable telephone with the highest priority to disable its microphone, wherein said controller enables speech to be picked up by said hands-free microphone and transmitted to the portable telephone with the highest priority through said audio/data transceiver.

17. The rearview assembly of claim 16, wherein said display is configured to display the identity of the portable telephone with the highest priority.

18. The rearview assembly of claim 16, wherein said display is configured to display the identities of all of the portable telephones having predetermined identification codes that are within the range of the audio/data transceiver.

19. The rearview assembly of claim 13, wherein said controller is operative in a pairing mode and an operational mode, during the pairing mode, said controller searches for, discovers and acquires a unique identification code of a device with which said audio/data transceiver is to be paired, during the operational mode, said controller determines whether a device having the unique identification code is within the range of said audio/data transceiver and exchanges data with the device through said audio/data transceiver, also during the operational mode, said controller prevents the exchange of certain data with detected devices that are not paired with said audio/data transceiver.

20. The rearview assembly of claim 19, wherein said display is configured to display the identity of a device with which said audio/data transceiver is paired.

21. A vehicle rearview assembly for providing an image of a scene to the rear of the driver of the vehicle, said rearview assembly comprising:
