Pairing Bluetooth HFP cradle with Audio 20

[djgilly]

It's possible that your phone isn't compatible? You don't give details of your car either, which may make a difference, as there are two different systems used in Mercs. I know very little about these things, but these details will help those who know more. Model and year? I do appreciate that you have probably checked these things.

However in the manual (Copy below) the instructions for Audio 20, starting at #17 don't make it clear on which button on the wheel you need to press to 'confirm'. Have you tried pressing the + button on the wheel to 'confirm'? (Just an idea, a shot in the dark).

P.S. Hello and welcome.

Thanks Grumpy!

yes, I've wondered about compatibility but have seen (can't remember where now) someone report that the phone is compatible. The car is b class 57 plate and I'm told that the cradle should work no problem (phone compatibility issues aside).

I think my phone needs remote sim access or remote sim access profile, but i can't find out whether it has. this website seems to suggest that it shouldn't be a problem:

Compatibility

Yes, I have tried all buttons on both the unit and steering wheel, but the only one that seems to confirm is the call button. But I do find that strange in itself, because when I press it once the pin has been entered, it states "dialling" and then I get the decending tone (which according to the cradle manual means that pairing has failed).

Thanks for your help.
