Touchscreen Controls for a Connected Computer (MFD models)
NOTICE
To prevent corrosion due to moisture, you must use Garmin GPSMAP accessory cables when connecting the
chartplotter to the computer. Using different cables voids your warranty.
You can connect the chartplotter to a computer to see the computer screen on the chartplotter touchscreen
and control the computer using the chartplotter touchscreen. To see the computer screen, you must connect
the computer to the HDMI IN port. To control the computer, you must connect the computer to the USB port.
The Garmin HDMI accessory cable (010-12390-20) is 4.5 m (15 ft) long. If you need a longer cable, you should
use an active HDMI cable only. You need an HDMI coupler to connect the two HDMI cables.
The Garmin USB accessory cable (010-12390-10) is 4.5 m (15 ft) long. If you need a longer cable, you should
use a USB hub or USB repeater extension cable only.
You must make all cable connections in a dry environment.
