*Press Menu twice to get into the Main Menu System ...
*Cursor over to the Setup tab ...
*Cursor down to User Mode ...
*Set User Mode to Advanced ...

Then go under the Sonar tab to look for a Menu item called "Connected Transducer" ...

If there is no "Connected Transducer" Menu = there are no other xducer options for that model ...

I offer the above info vaguely because I've never actually had the HELIX 5 DI in my hands to check for myself ...
