I have a 3g iPhone paired with my zumo 550 and autocom blue tooth dongle. Everything works perfectly except speech making mobile calls. I can hear the dial tone and hear the answer at the other end but the recipient cannot hear me talking. Any ideas??
Zumo and iPhone both correctly list paired devices.

. I had a problem with the volume which turned out to be my own fault as I had turned the autocom unit down instead of up
. While I was trying to sort it I found that if the dongle was plugged into the wrong socket then I could hear the caller but they could not hear me. This sounds like the same problem that you are having so it could be that you need to change aux sockets. Then again I could be wrong again
. I have tried changing the the aux ports over and seem to get better sound (stereo music) from the Zumo when it is connected to port 2 but then the phone won't work properly.
