Important Safety Information

 WARNING

See the 

Important Safety and Product Information

 guide in the 

product box for product warnings and other important 

information.
When connecting the power cable, do not remove the in-line 

fuse holder. To prevent the possibility of injury or product 

damage caused by fire or overheating, the appropriate fuse 

must be in place as indicated in the product specifications. In 

addition, connecting the power cable without the appropriate 

fuse in place will void the product warranty.

Understanding the Components

The GPSMAP 8500 system can be set up in different ways, depending on your needs and the layout of your boat.
The GPSMAP 8500 is the brain of a GPSMAP 8500 system and it connects to other devices and GPSMAP 8500 systems on your 

boat. The GPSMAP 8500 can be controlled by a connected GMM™ monitor, a connected GRID™ input device, or combination of 

the two.
