Service
1. Verify that the customer's cell phone is on the Bluetooth compatibility list. You will find the latest release on www.audiusa.com/bluetooth.
2. Proceed to the appropriate section based on vehicle equipment.
Tip: On certain phones, if the connection has already been established, there are additional confirmations that need to be accepted to
automatically re-pair. This includes Blackberry and some Android devices.
MMI3G, MMI3G+, RMC:
1. Verify Bluetooth is turned on within the Bluetooth menu on the phone and in the vehicle.
2. Bluetooth visibility selections within the Bluetooth menu will affect pairing functionality if the pairing is initiated from the phone:
Off: The vehicle cannot be seen by any Bluetooth device.
Auto: The vehicle is visible to Bluetooth devices up to a speed of 5km/h and up to 5 minutes after switching on the ignition.
On: The vehicle is always visible regardless of speed or time from ignition.
If pairing is initiated from the vehicle, the above settings do not apply.
3. During pairing a PIN will be generated or requested from the user. To pair the phone to the vehicle simply confirm the PIN on either device
depending on the pairing method.
Tip: If the vehicle and the mobile phone support the connection method "Secure Simple Pairing" (MMI3G+ from 22/2011, RMC from
45/2010), then a Bluetooth connection can be made while driving. This method provides a 6 digit PIN which appears on both the vehicle and
mobile phone. Simply confirm the two PINs are the same to connect.
4. If all values are set correctly, and the phone still will not connect, please follow standard diagnosis procedures.
UHV CAN, MMI 2G:
1. Verify Bluetooth is turned on within the Bluetooth menu on the phone.
2. The pairing process must be completed from the phone, as there is no option to search for phones from the MMI.
3. With MMI 2G the vehicle is only visible up to 5km/h and up to max. 5 minutes after switching on the ignition.
4. With UHV CAN the vehicle is always visible for vehicles built after CW 22/2008. For vehicles built beforehand it is visible up to 5km/h and
up to max. 5 minutes after switching on the ignition.
5. The default PIN is 1234. In MMI 2G the PIN can be changed in the Bluetooth Settings menu. In RNS-E vehicles, under Telephone Settings.
88
The PIN cannot be changed in other radios.
6. If the initial connection still fails, for UHV CAN and MMI 2G vehicles verify in 77 - Telephone Transceiver that Adaptation channel 133 is
on 1 (Bluetooth enabled) and channel 134 is on 0 (cradle is not installed). In addition, for MMI 2G equipped vehicles: Verify also in 07 -
Display/control unit that adaption channel 12 is on 2.
7. If all values are set correctly, and the phone still will not connect, please follow standard diagnosis procedures.
