HDMI Video Considerations
To prevent corrosion due to moisture, you must use Garmin GPSMAP accessory cables when connecting the
chartplotter to the video source or display. Do not connect a media player stick directly into the back of the
chartplotter. Using different cables or connecting a media player stick into the back of the chartplotter voids
your warranty.
This chartplotter allows video input from HDMI video sources, such as a Chromecast
player. You can view protected HDMI content (HDCP content) on the chartplotter screen, but are limited with
how you can view that content on additional devices.
Through the HDMI OUT port, you can display the chartplotter on an external screen, such as a television or
monitor. On a GPSMAP 8000 series chartplotter, you cannot view HDCP content on an external screen. On a
GPSMAP 9000 series chartplotter, you can view HDCP content on an external monitor that supports industry
HDCP standards.
HDMI video is shared across the Garmin Marine Network and across the Garmin BlueNet network, but it is
not shared across the NMEA 2000 network. HDCP content cannot be shared across the Garmin network to
GPSMAP 8000 series or older chartplotters. HDCP content can be shared by a GPSMAP 9000 series chartplotter
only to other GPSMAP 9000 series chartplotters connected to the Garmin BlueNet network.
The Garmin GPSMAP HDMI accessory cable 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.
You can use an adapter cable to power a media player stick using a USB port on the chartplotter. The USB port
on a GPSMAP 8000 series chartplotter and the USB DRD port on a GPSMAP 9000 series chartplotter can supply
up to 2.5 W to power a media player stick. The USB port on a GPSMAP 9000 series chartplotter can supply up to
4.5 W to power a media player stick
You must make all cable connections in a dry environment.
