Hi barab63,
I'm not familiar with the Interphone F5MC, and there are many different ways of configuring things,
but I would suggest starting with the following :
( Read the text marked ** below first as that may be a quick fix if everything is already set up ! )
In addition to checking the Trophy Audio Software version is up to date ( Version 1.04E ),
check that your F5MC has the latest Firmware - details on Interphone's web site here :
Interphone F5MC Bluetooth Helmet Headset( You can also download the Instruction Maual from there is you need it ).
First of all go into the Trophy Menu and Delete all Pairings so you start from scratch.
Similarly, Delete Pairings from your S5MC.
The Trophy Audio system has two "Channels" which are named "HEADSET 1" and "DEVICE 2"
( the numbers 1 & 2 refer to those 2 channels - there is no "HEADSET 2" or "DEVICE 1" )
Pair your S5MC to the Trophy first as "HEADSET 1" then Test to make sure that it works :
Select a radio Station and play it back through the Trophy Speakers
( so you know for sure there is something to hear )
then change the Output of the Trophy to HEADSET.
The audio SHOULD then be heard on your F5MC.
** If you don't hear anything it is probably because you need to press a button on
the F5MC to activate the incoming audio stream ( I had to do this on my older F3XT ).
( Try the "UP" button - one or more times - until you get to "Music Streamig"
and then press the MFB Button once ).
It can take several seconds for the Audio to come through after pressing the button so be patient !Once you have the audio coming through, Pair your Mobile Phone as "DEVICE 1",
and everything "should" work !
Cheers
