Cellular Telephone Description and Operation (without UE1): Notes
The mobile telephone control module offers the opportunity to hold phone conversations using a cellular telephone via a vehicle microphone and vehicle speaker system and to operate the most important cellular telephone functions via the infotainment system in the vehicle. The mobile telephone control module is available in two configurations, based on different radio types, mobile telephone control module low for base CD radio and a mobile telephone control module high for uplevel CD radios and navigation-systems. Both modules basically provide the same features:
- Call lists
- Call handling
- Steering wheel control
- Status messages
- Phone book
- Bluetooth
- Speech recognition, including adaptive echo and noise reduction algorithm
An additional base plate and cradle is available for specific cellular telephones, available as an option. It provides charging of the cellular telephone and a connection to the outside antenna. All cellular telephone interaction and data transmission to mobile telephone control module is done via Bluetooth. In order to create a connection between the mobile telephone control module and the infotainment system, the mobile telephone control module must be switched on and the cellular telephone logged in. The mobile telephone control module switches itself on and off via the ignition. If the ignition is switched off the mobile telephone control module can be switched on and off via the infotainment system. When a telephone connection is active, the radio sound is switched off. When the telephone connection has ended, the radio sound is switched on again.
