On AudiTTs with a car telephone kit, you can choose between three different telephone modes to optimise the network response. In Automatic mode, the car telephone automatically switches between the GSM (2G), UMTS (3G) and LTE networks. This depends on network availability and reception and on the position of the AudiTT. In this mode, there might be restrictions when using Google Earth or Wi-Fi. With Telephony optimised, the car telephone kit registers with the GSM network (2G). In this mode, the reception is prioritised for making and receiving calls. There may be restrictions when using Google Earth or Wi-Fi. When you select the telephone mode Automatic or Telephony optimised, there may be network restrictions when you try to use Audi connect services and make voice calls at the same time. With Data service optimised, the car telephone registers with the GSM (2G), UMTS (3G) or LTE network depending on network availability and reception and on the position of the AudiTT. In this mode, the reception is prioritised for the use of data services. There may be restrictions when making and receiving calls. We recommend that you mainly use this setting in areas with good UMTS (3G) network coverage.

You can switch the MMI ring tone on or off using the Mute telephone function. Ring tones are played when you select the function Ring tone. Press the rotary pushbutton to store the selected ring tone. You can adjust the Microphone input level during an active phone call using the rotary pushbutton. For the settings Ring tone volume/Message volume, see link►.
