Without knowing the Phone.... check if it is capable of being used as a Media Player, with a USB output, if so, you should be able to connect it to the USB port in the Glove Box , or alternatively, assuming the Phone has Bluetooth A2DP profile etc ( I'd be surprised if it didn't ), Pair the Phone to your Trophy by Bluetooth :
Pair your helmet Bluetooth headset to the Trophy first as "Headset 1" then Pair the Phone to the Trophy as "Device 2"
Select Bluetooth as the audio source from the handlebar controls ( "M" button ) and your Phone music will then be streamed from your Phone to the Trophy audio system and on to your Bluetooth headset
