Changing Instrument Screen Options Data provided on an instrument screen is represented numerically. In many cases, a numerical value can be shown as an analog gauge or as a graph, and vice versa (not available on all instrument screens). To change the appearance of an instrument screen: • If the instrument screen is showing a number, select Menu > Show Gauge or Show Graph. • If the instrument screen is showing a gauge or a graph, select Menu > Show Number. To change additional options on an instrument screen: 1. From the instrument screen, select Menu. 2. To change the source sensor, select Source, and choose the sensor you want to use. For example, if you have a GPS antenna and a heading sensor, you can choose to show either GPS Heading (COG) or Heading from the heading sensor. 3. To change additional options, such as resetting an odometer, adding Trip Speed Graphics to a speed gauge, viewing a watertemperature graph, or adding fuel, select the option you want to change.
