A couple of things you can check :
Have the engine running and see if the Radio will turn ON - by pressing the Volume UP Button.
If not, check whether there is any Power at the Cockpit Stowage compartment USB Port -
which gets its Power from the Audio Unit.
If there is a Sat Nav connected to the dedicated Sat Nav Power supply socket
( behind and below the left mirror pod ) similarly check if it is getting Power.
remove the storage box under the Rider seat ( 4 x Torx screws and lift it out )
to access the Audio Unit. Check the Multi-Plug is pushed firmly in and latched in place.
Check the Fuse ( again ? ).
Disconnect the Main battery - leave for half an hour or more then reconnect it.
If you can get the Radio to switch ON, check the Software version
( although the Radio needs to be OFF to do this ! ) :
Radio Software Version :
Early US / Canada export models of the Trophy SE ( With XM Radio )
have / had a bug in the Audio Software that could allow the radio Unit
to stay switched ON after the Ignition has been switched OFF,
resulting in a drained main motorcycle battery.
An updated Software Version ( "1.04E" ) was released that fixes this problem,
and is available from authorised Triumph Dealers.
Anyone with the XM Radio fitted is advised to get the update !
You can easily check the Audio software version of your Trophy :
The Radio MUST be OFF when the Ignition is switched ON ....
Turn the Ignition ON ( but don't start the engine ) and check for "RADIO OFF" in the Display.
If it's ON, then turn it OFF ( Volume all the way down to Minimum, Mute and Off ),
Switch the Ignition OFF, then back ON again and confirm that "RADIO OFF" is now displayed.
Press and hold the "P" button until the "DIAGNOSTICS" menu is displayed.
Scroll to the S/W VERSION item, and press Select.
The Latest Version for US market is 1.04E - you have anything earlier ( such as 1.04A )
then get your authorised Triumoh Dealer to update it.
If all of the abive fails, then ittls backto the Seller to get them to sort it.
Cheers
