It's there, but hard to locate at first.
Notice the circular symbol in the top right of the screen.
Clicking once brings up several options, and clicking on it twice brings up other options.
symbol is for the alarm
, though greyed out if no gps is connected.
There is another path to this function that escapes my at the moment.
edit,.... the other path is through the configuration of PolarCom, which must be downloaded and used for gps integration. This provides the onscreen "dashboard" for speed, position, etc.
