Hi Trophy Tom,
Do you have the Audio Handbook ?
If not you can download it here :
Triumph Trophy SE HandbookAll the instructions are there to get XM Registered, Up and Running,
including information on how to access "Channel 0", which doesn't seem to be a "Channel" as such,
it is used to display the alphanumeric radio identification number, that you will need to activate your Subscription.
( That number is also displayed on the radio unit, and your Dealer
may also have a record of it ).
To receive Channels after commencing your Subscription,
you need to make sure the Trophy has a clear view of the Southern Sky,
so it can pick up the Satellite broadcast signals

Cheers
