Using built-in Bluetooth short-range wireless technology and the Palm Treo 650 smartphone, drivers of 2006 Audi A6 and A8 vehicles can make and receive calls totally hands-free using the car's MMI (Multi Media Interface) console, voice-recognition interface or steering-wheel controls.

With the Treo 650 smartphone, Audi drivers can take advantage of the Treo 650's advanced calling features without ever touching the smartphone. After initiating Bluetooth communications between the Treo 650 and the car, drivers can use the steering-wheel controls, MMI controls on the dashboard, or the optional voice recognition to do the following:

• Pick up or ignore incoming calls; 
• Dial outgoing calls; 
• View active call status, including caller ID; 
• View the Treo 650's call history; 
• Dial from Treo 650 favorites, speed dials, or call logs; 
• Access Treo 650 voicemail; 
• Manage multiple incoming calls; and 
• View carrier information, including signal strength and roaming status.
