Garmin gpsmap 5212 User Manual

Configuring the Device

Speed Sources—specify the sensor used for Wind numbers and Fuel Economy. Touch 

 or 

 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.

From the Home screen, touch

.

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 

 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.
