Bluetooth communications between Apple iPhone 3G and an Audi mobile telephone preparation system

A few weeks back I had the use of a 2008 Ford Mondeo for a week and I wrote about my experiences of pairing my Apple iPhone 3G with the Ford Audio system. This morning, I got to play with a new Audi A4 Avant (2.0 TDI 170PS) for a few hours (it was fun – I will be ordering one soon) and I repeated the experiment with the iPhone 3G.

I didn’t have time to collect screenshots/photos but this is a quick summary of what I was told by the dealer/verified to be true (this car was an S line model and was fitted with the Audi Mobile Telephone Preparation Low and Audi Music Interface options):

  • The iPhone 3G will happily pair with the Audi’s audio system via the Mobile Telephone Preparation Low option but it is useful to know that: the pairing needs to occur within 30 seconds of opening the car and inserting the key (i.e. activating the car’s systems); the car identifies itself with a device name of handsfree; and the PIN for pairing is 1234.
  • Once paired, calls will ring the iPhone and the car simultaneously. The Bluetooth logo and signal strength are displayed on the Audi Multi Media Interface (MMI) display.
  • The car can access the iPhone 3G’s list for recently dialled numbers, missed calls, etc. but full directory integration does not appear to be available. Numbers can be dialled from the car’s systems (and the call placed on the iPhone). I did not have access to a vehicle with voice control system so this was not tested.
  • To use the iPhone as an iPod with the Audi Music Interface (AMI), a special cable is required (which I did not have access to).
