R171 Audio 20 (Option 523) MY 2004

[Gollom]

Anybody know the actual spec of this unit? I.E. Does it include Bluetooth a standard? If it make a difference the car has 819 - CD Changer

What are my upgrade options?

The VIN decoder says 386 - Mobile Pre-Installation (MTUS) What is this?

Thanks

It may have bluetooth but it wont work! On the early 171s it was deactivated as I understand it because it did not work properly - or so I was told. Our 2005 claims to have Bluetooth but it is disabled. The mobile preinstallation has a connector thing in the top section of the centre armrest. This is for a phone cradle or Bluetooth module (MB or Viseeo) to connect to. Get a bluetooth cradle and then you will be fine.
