Hi Motocheck, I have almost identical set up to you and have connected my devices in the same way. In that setup I have noticed that when the zumo want's to provide an audio message it cuts across the DMC comms rather than quietening down the comms to provide an instruction. I believe it is doing this as it is on the 2nd PT phone channel and so the PT see's it as a call coming in and won't mix the audio making it hard to hold conversations when the Zumo wants to say something. Have you had similar experience and/or found a way to hook all 3 devices up so it just works and mixes the audio as you would expect? I find whatever I do I either loose some functionality such as shuttle control from the headset if phone to 2nd PT channel or the audio cut across issues as described above.
