Connecting the Device to a Remote GPS Antenna
This device has an internal GPS receiver, but some installations, such as a flush-mount installation, may not allow a view of the sky needed to calculate your GPS position. In this situation, you can install a Garmin® external GPS antenna and connect it to the device to provide GPS information.
Devices that can receive information from a Garmin external GPS antenna have a port labeled EXT GPS.
- Follow the instruction provided with your Garmin external GPS antenna to install it on your boat correctly.
- Route the antenna cable to the back of your device, away from sources of electrical interference.
- Connect the antenna cable to the EXT GPS port on your device.
