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.  During Standby mode, a countdown appears on the Radar page (and on the top status bar) counting down as the scanner prepares to 

operate. 

4.  Once ready, hold 

FCTN until “Do you want to begin radar transmission?” appears and release.

5.  When safe to do so (personnel clear of radar beam path), highlight ‘Yes’ and press 

ENTER. The scanner spins up and is now operating.

It may be necessary to adjust the bearing of the radar picture shown on the screen. First, using a magnetic compass, take an optical bearing of a 

stationary target located within viewable range. Measure the target bearing on the radar. If the bearing deviation is more than +/- 1°, then do the 

following to correct for the offset:

1.  From the Radar Page, press the ‘

ADJ’ key to display the Adjustment Menu.

2.   From the Adjustment Menu, select ‘Setup’ and press 

ENTER.

3.  Using the 

ARROW KEYPAD, highlight the ‘Front of Boat Offset’ slider and press ENTER.

4.  Press Left on the 

ARROW KEYPAD to adjust to a negative value or press Right to adjust to a positive value. The preview window below 

changes as you adjust the slider.

5.  Once an offset has been determined, press 

ENTER to save and press QUIT to return back to the Radar Page. Your new Garmin Marine 

radar is now ready to use! Refer to the GMR 20/40 Owner’s manual (190-00457-00) for details on operating the scanner.
