I see that I can set the buzzer pattern on the non-OBD XIRGO via SMS commands but how do I actually activate the buzzer so I can hear it? Enabling the two pattern did not activate the buzzer itseelf.

Once you have set up the buzzer to function, apply power to the ‘ignition’ input.

The functionality is intended to remind the driver, for an annoyingly long enough duration, of some cause.  E.g. late payment etc…

Does it mater if I have VIRTUAL IGNITION enabled or not?

Answered my own question

Would you mind sharing your findings so others can benefit? Thanks!

The buzzer did not sound when in VIRTUAL IGNITION mode. Makes sense that it must be in WIRED IGNITION mode in order to sound the buzzer using the Ignition Wire from the device.
