Changing the Settings Turning Safe Mode Off and On Press Menu three times. Then select General > Safe Mode. When Safe Mode is turned on and the vehicle is moving, Safe Mode disables all navigation system functions that require significant operator attention and could become a distraction while driving. Changing the Coordinates Settings Press Menu three times. Then select General > Coordinates. Position Format-change the appearance of your coordinates. Your current position is viewed on the GPS in the form of coordinates. Because different maps and charts use different position formats, you can choose the correct coordinate system for the type of map you are using. Map Datum-select the map datum to be used by your GVN 52. If you are navigating and comparing the GPS coordinates to a map, chart, or other reference, set the map datum in your GVN 52 to the same datum as the map to ensure the most accurate navigation. Setting Audio Mute Polarity Press Menu three times. Then select General > Audio Mute Polarity. This is used for muting your radio when your GVN 52 plays navigation prompts. Select Low or High, depending on your radio configuration. See your radio's instruction manual for more information. Note: This setting is used only on radios that can switch to Aux audio based on an external signal. 36 GVN 52 Owner's Manual
