WELCOME Thank you for choosing the Garmin GMR 20/40. The GMR 20/40 utilizes the performance of Garmin radar and provides overlay and color information when combined with a marine Multi-Function Display (MFD).

Scanner Installation The following section covers the installation and setup of the GMR 20 (2 kW) and GMR 40 (4 kW) Marine Radars. The GMR 20 and 40 only operate with components of the Garmin Marine Network with compatible MFD (Mulit-Function Displays). See your Garmin dealer or the Garmin web site for more details. To complete the installation, you will need the appropriate fasteners, tools, and mounts. These items should be available at most marine dealers.
Mounting the Scanner 1. Once a suitable mounting location has been determined, verify that the mounting hole locations are aligned fore and aft, then drill four 9.5 mm (0.37”) mounting holes referencing Figure 1 below. (This step is not necessary if you are using a pre-drilled Garmin compatible or Raymarine mount.) 2. Remove the supplied M8x30 bolts, flat washers, and spring washers (4 each) from the bottom of the scanner unit. Do NOT remove the outer case bolts.
Final Wiring Connections Once the scanner is installed and the cable routed, you are ready to connect the Power and Marine Network. 1. Connect the Black Ground (-) wire to the vessel’s negative power terminal. 2. Connect the Power (+) wire (with fuse holder) to the vessel’s positive power terminal. 3. For a stand-alone network (MFD and Radar only), attach the RJ-45 Marine Network Cable to the RJ-45 socket on the back of the MFD. For an expanded network (MFD, Radar, GMS 10, etc.
Powering on the System Once successfully installed the scanner is ready to be powered on. 1. On the MFD (Multi-Function Display), press the red Power button. This will automatically power on the scanner. The Welcome Page appears showing the GMR 20 or 40 as a detected Network Connection. 2. Press ENTER when “I Agree” turns yellow, then press PAGE until the Radar Page appears. 3.
