Configuring the Device Speed Sources-specify the sensor used for Wind numbers and Fuel Economy. Touch Wind or Fuel Economy to toggle between Water (from a water-speed sensor) and GPS (from the calculated GPS speed). Auto Guidance-sets the Automatic Guidance parameters for your boat: • Safe Depth-sets the minimum depth (chart depth datum) to allow when calculating an automatic guidance path. A safe depth of less than one meter is not allowed when using Automatic Guidance. • Safe Height-sets the minimum height (chart height datum) of a bridge that your boat can safely travel under. • Shoreline Distance-set how close you want to travel near the shore: Nearest, Near, Normal, Far, or Farthest. This is used by the automatic guidance calculation to determine how close to the shoreline you want the automatic-guidance line to be. Changing this while navigating an automatic-guidance line will recalculate the path. Configuring the Device Configuring Units of Measure From the Home screen, touch Configure > Preferences > Units. System Units-global setting that defines individual units of measure at the same time. Statute (mh, ft, ºF), Metric (kh, m, ºC), Nautical (kt, ft, ºF), or Custom. Touch Custom to individually define units of measure for: • Depth-individually set the units of measure for depth to Feet, Fathoms, or Meters. • Temperature-individually set the units of measure for temperature to Fahrenheit (ºF) or Celsius (ºC). Note: You must be receiving NMEA Sonar depth data or using a Garmin sounder module to view depth and temperature information. • Distance-individually set the units of measure for distance readings (Miles, Kilometers, or Nautical Miles). • Speed-individually set the units of measure for speed readings (Miles Per Hour, Kilometers Per Hour, or Knots). • Elevation-individually set the units of measure for elevation readings (Feet or Meters). • Volume-individually set the units of measure for volume readings (Liters, US Gallons, or UK Gallons). • Pressure-individually set the units of measure for gauge (kPa or psi) and atmospheric (Millibars or Inches of Mercury) pressure readings. Heading-set the reference used in calculating heading information. • Auto Mag Var (Automatic Magnetic Variation)-automatically set the magnetic declination for your location. • True-set true north as the heading reference. • Grid-set grid north as the heading reference (000º). • User Mag Var-set the magnetic variation value. Position Format-set the coordinate system in which a given location reading appears. Do not change the position format unless you are using a map or chart that specifies a different position format.
