WARNING! Ensure all power is OFF during installation. Drilling into the boat structure requires caution to avoid damaging hidden wiring or tanks. Seal all holes to prevent water intrusion.
Apply power to the unit; follow on-screen prompts.
CAUTION! Do not turn off the unit during initial GPS satellite acquisition or system calibration.
Access menus via the MENU button. Use the ROCKER to navigate and ENTER to select.
Front Panel Buttons: POWER, PAGE, ROCKER (up/down/left/right/ENTER), MENU, ZOOM IN, ZOOM OUT.
Main Pages: Access via PAGE button - Chart, Sonar (if connected), Compass, Highway, Main Menu.
Settings Menu Categories: System (Units, Time, Alarms, NMEA), Navigation (Routing, Tracks, Waypoints), Chart (Presentation, Data Fields), Sonar (Setup, Gain, Frequency).
Quick Keys: Press and hold MENU from any page for quick access to common settings like backlight and data fields.
NMEA 0183 Devices (Autopilot, VHF, etc.): Connect transmit (TX+/TX-) and receive (RX+/RX-) wires from the device to the corresponding terminals on the chartplotter's power/data cable.
NMEA 2000 Network: Connect the chartplotter's NMEA 2000 drop cable to the boat's NMEA 2000 backbone using a T-connector.
Sonar Module: Connect a compatible Garmin sonar module (e.g., GSD™ series) to the network or directly via its designated port on the power/data cable.
SD Card: Insert map or data SD card into the slot on the side of the unit.
Tip: Label all wires during installation for future troubleshooting.
Supports detailed marine navigation with waypoints, routes, and tracks.
WARNING! Always use official paper charts as the primary means of navigation. This electronic chartplotter is an aid to navigation only.
(Requires connection to a compatible Garmin sonar module and transducer.)
Access the Sonar page via the PAGE button. Displays water depth, bottom contour, and fish arches.
Key Settings: Adjust Gain, Frequency, and Range for optimal display. Use the Fish ID feature to mark potential targets.
Alarms: Set shallow and deep water depth alarms.
Disconnect power before cleaning. Use a soft, lint-free cloth dampened with fresh water. A mild soap solution can be used for stubborn stains. Rinse with a cloth dampened with fresh water and dry thoroughly.
CAUTION! Do not use harsh chemicals, abrasive cleaners, or compressed air. Do not spray liquids directly onto the unit. Ensure the unit is completely dry before reapplying power.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Unit will not power on | No power, blown fuse, incorrect voltage | Check connections at battery and unit. Verify fuse is intact. Ensure voltage is between 10-32 V DC. |
| No GPS signal | Poor sky view, first-time acquisition | Move to an open area. Wait up to 30 minutes for first fix. Ensure no metal obstructions overhead. |
| Chart not displayed | SD card issue, wrong location | Ensure SD card is fully inserted. Zoom out to see basemap if detailed charts are missing for your area. |
| No depth reading (sonar) | Transducer not connected/no power, air bubbles | Check all sonar module and transducer connections. Ensure transducer is submerged and not blocked by hull debris or air bubbles. |
| NMEA devices not communicating | Incorrect wiring, wrong baud rate | Verify wiring matches NMEA 0183 diagram. Check that baud rates in the chartplotter settings match the connected device. |
| Screen is dim or unreadable | Backlight setting, direct sunlight | Adjust backlight intensity in the System Settings menu. Use the sun cover if provided. |
