Introduction > Important Information and Battery Warnings Important Information MAP DATA INFORMATION: One of the goals of Garmin is to provide customers with the most complete and accurate cartography that is available to us at a reasonable cost. We use a combination of governmental and private data sources, which we identify in product literature and copyright messages displayed to the consumer. Virtually all data sources contain some inaccurate or incomplete data.
Getting Started > Unit Overview Getting Started Unit Overview The GPSMAP 378/478 is an all-in-one, versatile color chartplotter and automobile navigator—perfect for land or water. This portable GPS navigator features a 256-color TFT display that is easy to read in bright sun and includes built-in g2 cartography (GPSMAP 478) or built-in lake cartography (GPSMAP 378), and preloaded City Navigator NT® to provide you with automatically generated turn-by-turn directions.
Getting Started > Charging the GPSMAP 378/478 Charging the GPSMAP 378/478 Before using the GPSMAP 378/478, you might need to charge the battery. Plug the power cable into an external power source to charge. You can use the unit while it is charging. Using Charge Mode If you want to charge the battery when you are not using the unit, you can put the unit into Charge Mode. To charge the unit’s battery: 1. Lift the rubber weather cap to expose the power connector on the back of the unit.
Getting Started > Turning On the GPSMAP 378/478 Turning On the GPSMAP 378/478 Before you turn on the GPSMAP 378/478, be sure the antenna is up as shown on page 1, and it has a clear and unobstructed view of the sky to receive satellite signals. The first time you turn on your GPSMAP 378/478, the GPS receiver must collect satellite data and establish its current location.
Getting Started > Getting Satellite Signals Getting Satellite Signals After you turn on the GPSMAP 378/478, the unit automatically begins searching for satellites. The GPS Page appears while the unit is gathering satellite signals and acquiring a fix, which should take only a few minutes. While the GPSMAP 378/478 is getting satellite signals, the GPS Page shows the status as “Acquiring Satellites.” GPS Tab Note: While acquiring satellites, the Map Page might show the wrong location, such as China.
Getting Started > Getting Satellite Signals The progress of satellite acquisition is shown in three stages: • No signal strength bars—the receiver is looking for the satellites indicated. • White signal strength bars—the receiver has found the satellite and is collecting data. • Green signal strength bars—the receiver has collected the necessary data from this satellite.
Getting Started > Getting Satellite Signals GPS Options Press Menu twice to open the Main Menu. Use the ROCKER to highlight the GPS tab. Press Menu to open the options menu. GPS Tips While the receiver is gathering information, your location on the map might appear different from where you are actually located.

The graph reads from right to left so that the most recent temperature measured appears on the far right side of the graph. The dotted lines within the graph indicate intervals in the temperature scale and the duration of time. To view temperature information, you must select Temp or Temp, Spd as the transducer type on the Setup sub tab.
Setting up and Using Sonar > Understanding Sonar Understanding Sonar The transducer mounted on your vessel transmits sound waves toward the bottom of the water in a cone-shaped pattern. When a transmitted sound wave strikes an underwater object—such as the bottom, a structure, or a fish—sound is reflected back to the transducer. The transducer collects the reflected sound waves and sends the data to the GSD 21 Sounder Module and then to the GPSMAP 378/478 to be processed and shown.
Setting up and Using Sonar > Understanding Sonar Transducer Coverage The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth. The wide Coverage cone angles (40°) associated with low frequencies (50 kHz) provide diameter a large coverage area for finding fish within a coverage width that is approximately 2/3 of the water depth. However, this also means that wide cone angles produce less bottom detail and resolution.
Setting up and Using Sonar > Understanding Sonar Whiteline The GSD 21 Sounder Module can help you determine whether the bottom is hard or soft. When the sonar sound waves are reflected back by the bottom, a hard bottom returns a stronger signal than a soft bottom. A thin whiteline indicates a softer bottom, while a thick whiteline indicates a harder bottom. Normally, a red line is used to show the point where water meets the bottom.
