2006 525D + Nokia + Bluetooth - Falkirk Bairn
You pay £30K+ for a nice car and about £1000 to get Bluetooth as an extra & it works with your 2 year old Nokia phone.

12 months later - You pay Nokia £250 for a new model phone with Bluetooth.

And they will not talk to each other.

I know research before replacing the phone might have been a good idea but both support Bluetooth 2.0 - the fact that they do not communicate is infuriating.

Any tips on where to go, who to ask?

BMW & Nokia seem to shrug their shoulders

Have you checked the Nokia support forums? Or forums on other sites like Expansys?

I have just had a similar problem with an upgrade Samsung and the bluetooth radio it was the radio that was at fault it was remembering the old phone, had to read the intructions a few times to get my head round it but it did work in the end.
