46. 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;
at least one hands-free speaker associated with said mounting structure for receiving an audio signal from 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. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)

58. 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. - View Dependent Claims (59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72)

73. 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 associated with said mounting structure for transmitting and receiving wireless audio and data signals to/from a portable device having a similar audio/data transceiver; and
a control circuit coupled to said audio/data transceiver, said control circuit being operative in a pairing mode and an operational mode, during the pairing mode, said control circuit searches for, discovers and acquires a unique identification code of a portable device with which said audio/data transceiver is to be paired, during the operational mode, said control circuit determines whether a portable device having the unique identification code is within the range of said audio/data transceiver and exchanges data with the portable device through said audio/data transceiver, also during the operational mode, said control circuit prevents the exchange of certain data with detected portable devices that are not paired with said audio/data transceiver. - View Dependent Claims (74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85)

86. 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 the mounting structure for providing an audio signal to said audio/data transceiver;
at least one hands-free speaker for receiving an audio signal from said audio/data transceiver; and
a control circuit coupled to the audio/data transceiver, said control circuit determines whether portable telephones having predetermined identification codes are within the range of the 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 control circuit 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 control circuit 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. - View Dependent Claims (87, 88, 89, 90, 91, 92, 93, 94, 95, 96)
