Appendix 

The lens on the screen is coated with a special anti-reflective coating 

that is sensitive to skin oils, waxes, and abrasive cleaners. Cleaners 

containing ammonia, alcohol, abrasives, or anti-grease detergents 

will harm the anti-reflective coating. It is important to clean the lens 

using an eyeglass lens cleaner (that is specified as safe for anti-

reflective coatings) and a clean, lint-free cloth.

The following GPSMAP 400 and GPSMAP 500 series chartplotters 

are NMEA 2000 certified and can receive data from a NMEA 2000 

network installed on the boat.

GPSMAP 451/451s  

GPSMAP 526/526s

To connect one of these chartplotter to an existing NMEA 2000
