Hi ColinM,
In addition to what trophied says (

) check that your Trophy has had the Audio Software update,
as there was definitely a Bluetooth "issue" although not ( currently ) reported to have affected the
Bluetooth Signal strength, it was to do with the Module not powering down when the Ignition was turned off,
resulting an a flattened motorcycle battery.
You can check the Software Version you have by :
To check the Audio Software Version :
1. Turn the ignition to ON position (don’t start the bike) and wait for the screen to display.
2. Make Sure “Radio Off” is displayed on the screen.
( If the radio is on, turn it off <Volume Down all the way to OFF>
and then turn the ignition off and back on again ).
3. Press and hold the (P) Preset button until diagnostics menu is displayed.
4. Press and release the scroll button until S/W Version is highlighted.
The latest Version for US markets should be 1.04E
