2 GPSMAP 620 and GPSMAP 640 Owner’s Manual
Getting Started
CAUTION
The ball-socket adapter on the GPSMAP 620 and GPSMAP 640
is not compatible with Garmin automotive mounts other than the
included mount. Do not mount the device on a windshield.
Notice
When you remove the GPSMAP 620 or GPSMAP 640 from the
marine mounting bracket, dry the metal contacts and use the
attached weather cap to prevent corrosion.
Using the Mounting Bracket
Notice
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 automotive-mount 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.
NOTE: To mount the GPSMAP 620 or GPSMAP 640 into your
boat console, purchase the GPSMAP 600 Series Flush Mount Kit at
www.garmin.com.
To install the automotive mounting bracket in your car:
1. Place the automotive-mount base on your dashboard, 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
dashboard due to dust and dirt buildup, wipe it clean using a wet
cloth.
To place the GPSMAP 620 or
GPSMAP 640 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.
4. Flip down the locking tab to
hold the device in the mounting
bracket.
To remove the device 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.
