I've a crazy problem that I think must be down to the configuration of my steering wheel and command unit buttons, but any advice appreciated.
I have a Viseeo MBU-2 installed on a second hand 2008 ML320 Sport. Bluetooth pairing works fine, although I think I have too many contacts to sync.
Once paired I can dial a call either using my phone keys or the command keys, and i can hang up a call using either my phone buttons or the steering wheel or command buttons.
I can press a button on the bluetooth adapter and this starts voice recognition, which works fine and connects to the contact.
However, and here's the problem, when I get an incoming call and use either the steering wheel or command to answer the call, the call connects but I can't hear the caller and the caller can't hear me. I can finish the call using the steering wheel or command buttons.
So in brief it looks like all bluetooth functionality is working, but there seems to be a configuration issue with the command and steering wheel buttons.
Would really appreciate help, but don't call as I can't answer
