I'm using the Bluetooth system on the MMI on my 05 A8, but I can't seem to use call waiting. My phone has it for sure, but when another call comes in, my only option is to "replace" the current call or "ignore" the new one. I also noticed that my MMI won't download the directory from my phone. Is this a phone compatibility issue, or just how the MMI works? Thanks.

 

I can't get my 05 A8L to download my phone book either. I have an IPHONE.
haven't tried call waiting yet. - Have you tried to use your phone to switch the call
not the MMI? - you know your phone controls work in conjunction with the MMI.

 

yeah ^ is right you have to use your phone to put the current call on hold while you take the other and swap back on your phone. MMI will just drop the first call
