It has been well discussed on how difficult it is to get U.S. dealers to understand where the audio software updates/ versions can be found, as it is a separate update from the ECM, and not a part of the dealer tool system used to communicate with our bikes. A local Triumph Dealer offered this information to post, so that U.S. customers can assist the dealer in finding the updates and instructions to perform the service.
Here's where Triumph dealers in the U.S. can locate the audio software updates and instructions for our Trophys:
Have them login to TOL (their dealer web portal),
Under the Service/ Technical pulldown menu, they'll find Diagnostic Software.
The audio updates are located in there.
Hope this helps everyone,
