Touchscreen Controls for a Connected Computer

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 recommended USB cable (010-12390-10) has a micro-USB end that connects to the chartplotter USB ports. This cable 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.
NOTICE

To avoid potential communication errors, you should use the correct USB cable for your chartplotter. You should not use an adapter to change the USB connector type on either of these cables.

You must make all cable connections in a dry environment.
