Garmin GPSMAP 8700 Installation Instructions Manual page 17

Touchscreen Controls for a Connected Computer
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 and to control the computer using a
touchscreen. To see the computer screen, you must connect the computer to the HDMI IN port and connect the
touchscreen to the HDMI OUT port. To control the computer using the chartplotter touchscreen, you must
connect the computer to the USB OTG port and connect the touchscreen to the USB HOST port.
The HDMI 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 OTG Adapter Cable (010-12390-11) is 1.8 m (6 ft) long and the Garmin USB 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.
