Getting Started

Inserting and Removing SD Cards

Your unit supports Secure Digital (SD) cards. Insert optional BlueChart® g2 Vision® SD cards to view high-resolution satellite imagery and reference photos of ports, harbors, marinas, and other points of interest. Use SD cards to transfer data such as waypoints, routes, and tracks to another compatible Garmin unit or a computer (page 40). The SD card slot is on the lower-right corner of the unit.

To insert the SD card, open the access door and press the SD card in until it clicks. Press the card in again and release it to eject it from the chartplotter.

Note: If you use an SD card to transfer waypoints from MapSource® or HomePort™, update to the most-current version by

clicking Help > Check for Software Updates, or check the Garmin Web site at www.garmin.com.

Use the Home screen to access all other screens. Press HOME from any screen to return to the Home screen.
