Hi Mordiglio,
I'm not familiar with the G9 system, but it may be that you cannot do what you want,
as I understand the G9 only has 2 Bluetooth Channels, and you're trying to use three channels.
( G9 to Trophy, G9 to Phone, and G9 to G9 ).
I think the Sena kits have a way round this by using a feature where the music ( or other input from the Trophy )
can be "shared" via the Intercom connection to a second Sena headset, without needing a third channel,
and can then switch between shared music or Intercom over that channel,
but I'm pretty sure the G9 doesn't have that feature.
What you could do, and what I do, is have the the first G9 channel helmet paired to the Trophy as Headset 1,
with the Rider's Phone paired to the Trophy as Device 2, and with the Zumo GPS hard wired.
The rider then receives all the Zumo Sat Nav voice instructions, Trophy radio,
and any other music device ( such as iPod ) connected to the Trophy, via the first channel of their G9,
with the ability to answer or reject calls on
their Phone via the handlebar controls and Instrument Panel display.
The Pillion pairs the first channel of their G9 to with their OWN Mobile Phone,
and the second channel of their G9 with the second channel of the Rider's G9 headset ( for the Intercom function ).
The Pillion is not then disturbed with the Sat Nav instructions, can choose their own preference of music,
and control their own incoming and outgoing Phone calls.
The Rider and Pillion can speak by Intercom when necessary.
