1.  Selecting a location.
2.  Installing the marine-mount base and connecting the marine-mount bracket to the marine-mount base.
3.  Connecting the marine-mount bracket to power.
Although they are not necessary to use the GPSMAP 620/640, these instructions cover two additional installation options:

•  Connecting the GPSMAP 620/640 marine-mount bracket to other NMEA 0183-compatible devices, such as a VHF radio with Digital

Selective Calling (DSC).

•  Connecting the marine-mount bracket to an external audio device.

Consider the following when you select an installation location:

The location should provide optimal viewing as you operate your vessel and allow easy access to the touchscreen.
The surface must be strong enough to support the weight of the GPSMAP 620/640 and protect it from excessive vibration or shock.
The location must be at least 17 in. (43 cm) away from a magnetic compass to prevent electromagnetic interference, which can cause 

inaccurate compass readings.
The location should not be exposed to extreme temperature conditions. The GPSMAP 620/640 is designed for operation from 5°F to 131°F 

(from -15°C to 55°C).

Install the marine mount on a console or overhead. Install the marine mount with the following tools and hardware (not included):

Three number 8 (4 mm) pan-head machine bolts with matching nuts and washers, or three number 8 

pan-head self-tapping screws. Do not use bolts or screws with a countersunk head.
