Bluetooth is the name given to a group of wireless technology standards that allow different types of electronic devices to interact via short-range radio waves. The Audi "Phone Preparation with Bluetooth" system utilises the Hands Free Profile. Not all Bluetooth-enabled mobile phones, however, are compatible with the Audi phone systems in the different models of Audi cars. The phones listed here are suitable for use within the United States.
Apple: The standard model iPhone as well as the 3G and 3Gs models can be used. Audi does not recommend the use of Apple software 4 on the last two models.
BlackBerry: 8000 series and 9000 series models. A restriction is that pairing must be initiated from the BlackBerry device on some models.
HTC: 12 models are compatible, including the Droid, Hero and Ozone. Some limitations are placed on phonebook displays.
LG Electronics: Most models are compatible, including the Chocolate, the enV series, the Glimmer, Rhythm and Touch. All have internal phonebook, call lists, provider name and signal strength displayed.

These networks provide phones, from different manufacturers, that are compatible with the Audi Bluetooth system: Alltel, AT&T, Nextel, Sprint, T-Mobile and Verizon.
This information is current as of October 2010. With the rapid changes in the phone manufacturing industry, more phones are being developed that are compatible with the Audi Bluetooth system. The Audi company websites, for the appropriate country, have a database that contains all mobile phones currently supported and any restrictions known, for each model of car that that they produce.
