I have the non-Nav version trip computer and would like to have some more info about it. I have learned to calibrate the range, outside temp, compass, and select the zone to be used for the compass. What I'd like to know is what can be done with the settings when you first press all three buttons (clock, trip, reset) simultaneously and wait for the display to show the entire led pattern. You can then cycle through several screens that look like settings, but I don't know what they are. Is there a manual availabel, preferably on-line?
