2002 S8, armrest phone - Am I missing something?

Hi Guys,

Just bought myself an S8, after 6 years of owning 4.2L A8s (2 of them: a ming blue one initially, and more recently a green one of the 'Sport' variety).

A few pics of the new motor:








The car has a RNS-D unit fitted, and a Nokia phone adaptor was fitted inside the armrest. I have an old Nokia 6310i that I'd like to use as a semi-permanent car phone, so it would be nice if I could make it work with the existing connections to make use of the charging facility and factory-fitted external aerial.

The Nokia adaptor that came with the car was for a different/smaller model, but I already had a Cullmann adaptor for the Nokia 6310i that I purchased a while ago in the hope of making it work with one of my previous A8s (turned out to have the wrong socket though, so it was never used).

With the adaptor in place and plugged it, if I dock the phone it recognises that it is docked (the car/hands-free symbol appears on the display, the earpiece is muted, and it begins charging), but no sound comes through the car's speakers when I dial. Is there something else I need to do or buy?

The previous owner fitted a Parrot unit, which will work with the phone, via Bluetooth, if I un-dock it. However, as soon as I dock the phone to charge it and make use of the external aerial, it refuses to connect via Bluetooth because it recognises that it is already connected to a wired hands-free unit.

Any help/suggestions greatly appreciated
