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.
These chartplotter models allow video input from HDMI® video sources, such as a Chromecast™ device or a Blu-Ray™ player.
You can view protected HDMI content (HDCP content) on the MFD chartplotter screen, and on the connected video source, but not on an external screen. You cannot view any HDCP content on a screen connected to the GPSMAP 8700 black box. If necessary, check the video source's manual to verify that HDCP can be turned off for the source.
HDMI video is shared across the Garmin BlueNet™ network and across the Garmin Marine 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.
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 the chartplotter can supply up to 2.5 W to power a media player stick.
You must make all cable connections in a dry environment.
