Can I see sonar with a GSD 20 or GSD 21 connected to a 3xxx series that is networked to another chartplotter?

If a GSD 20 or GSD 21 is connected to any of the GPSMAP 3xxx series devices, the sonar information can be transmitted through the Garmin Marine Network port of the 3xxx series.

Any other chartplotter (i.e. GPSMAP 4xxx, 5xxx, 6xxx, 70xx, 72xx, 74xx, 76xx, 84xx or 86xx) connected to the GPSMAP 3xxx series over the network, will be able to use the same sonar information to provide a sonar image.
