Expanded Network

NOTE: When using the GMR 18 with an expanded network, each network component must be installed according to its installation instructions. This diagram only shows how a GMR 18 radar communicates with an expanded network, and does not show the full wiring needs of the other network components.

Note: The GMR 18, Garmin MFD, and the other network components must be connected to a power source according to their installation instructions. This diagram only illustrates the network data connections.

Using the Radar

All functions of the GMR 18 radar are controlled using your Garmin MFD (multi-function display). See the Radar section of your MFD's manual for operating instructions. If your MFD's manual does not contain a Radar section, download the latest revision of the manual from http://www.garmin.com/support/userManual.jsp
