Introduction
Introduction
The GPSMAP® 620 is both a marine and an automotive GPSenabled navigation device. The automotive kit, which includes both
the automotive maps and the automotive mount is sold separately.
When you place the device in the mount installed on your boat,
it powers on in marine mode. When you place the device in the
automotive mount, it powers on in automotive mode.
This manual is divided in two sections; the rst section describes
how to use the GPSMAP 620 in marine mode, and the second
section describes how to use the device in automotive mode. The
sections are labeled with tabs along the edge of the page to help
identify the usage mode.

GPSMAP 620 Owner’s Manual 1
Getting Started
CAUTION: The ball-socket adapter on the GPSMAP 620 is not
compatible with Garmin automotive mounts other than the included
mount. Do not mount the device on a windshield.
Using the Mounting Bracket
CAUTION: Do not use the automotive mounting bracket in your
boat. The power connector and speaker assembly are not water
resistant, and therefore unsuitable for marine use. Additionally, do
not use the automotive-mount base in your boat. The automotivemount base does not connect to the dashboard using mounting
hardware, and therefore is not stable in marine conditions.
To install the marine mounting bracket in your boat, see the
GPSMAP 620/640 Marine Mount Installation Instructions.
To install the automotive mounting bracket in your car:
1. Place the automotive-mount base on your dash, and press
down on each of the four sides. The base bends and conforms
to your dashboard.
2. Snap the mounting bracket onto the automotive-mount arm.
3. Plug the vehicle power cable into a power outlet in your vehicle.
TIP: If the bottom surface of the automotive-mount slides on the
dash due to dust and dirt build-up, wipe it clean using a wet cloth.
To place the GPSMAP 620 in
the mounting bracket:
1. Flip up the locking tab on top of
the mounting bracket.
2. Fit the bottom of the device into
the cradle.
3. Tilt the device back until it
stops.
Placing the GPSMAP 620 in
4. Flip down the locking tab to

bracket.
To remove the GPSMAP 620 from the mounting bracket:
1. Flip up the locking tab on top of the mounting bracket.
2. Tilt the device forward, and lift it out of the mounting bracket.
