Select: Function selector button TEL > control button Settings > Telephone mode.
To optimise the network response you can choose between three different telephone modes in the settings of your car phone.
Automatic
The car telephone automatically switches between the UMTS network (3G) and the GSM network (2G) depending on the network availability and reception and on the position of the Audi A5. In this mode there might be restrictions when using Google Earth™ or Wireless LAN (WiFi).
Telephony optimised
The car telephone kit registers with the GSM network (2G). In this mode, the reception is optimised to suit users who use the car telephone kit predominantly to make telephone calls; however, there might be restrictions when using Google Earth™ or Wireless LAN (WiFi).
Data services optimised
The car telephone registers with the UMTS (3G) or GSM (2G) network depending on the network availability and reception and on the position of the Audi A5. In this mode, the reception is optimised to suit users who use the car telephone kit predominantly for data services; however, there might be restrictions when making telephone calls.
Note
- In areas with poor UMTS (3G) reception, the car telephone might switch to network search mode frequently when Data services optimised is selected for the telephone mode. Therefore we recommend that you use the Data services optimised setting mainly in areas with good UMTS (3G) network availability.
- 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.
