Garmin Marine Network Sharing Compatibility
Below is a breakdown of the Garmin marine device's ability to transmit and receive information across the Garmin Marine Network. The table refers to the built-in functions and features of the chartplotter. It does not include external devices such as radar, sonar modules, or SiriusXM antennas. New software versions and some settings are not shared across the marine network to chartplotters that no longer receive updates; refer to the Owner's Manual for instructions to access specific features.
The chartplotters listed will only share with other devices within the same table.
The GCV™ 10 sonar module, GCV™ 20 sonar module, and GMS™ 10 network port expander have additional Garmin Marine Network ports and will act as a network hub between compatible chartplotters.
For external component sharing capabilities, see External Devices Sharing Over the Garmin Marine Network.
ECHOMAP™ Combination Fishfinder Chartplotter Series

* The Marine network sharing port was unlocked to allow data sharing after software version 6.20. To verify the software version Select Settings > System > System Information > Software information.
** Not all ECHOMAP™ UHD2 chartplotters have a Marine Network port.

* Chartplotters with built-in Garmin Navionics+™ marine cartography cannot utilize BlueChart® g3 supplemental charts.
**Connection to another GPSMAP® 9000 chartplotter series does not require a Garmin BlueNet™ 30 Gateway, but connecting any other devices listed in this table will need the Garmin BlueNet 30 Gateway.
Examples of Networking Incompatibility
ECHOMAP chartplotters cannot share any data with a GPSMAP chartplotter
Devices preloaded with charts, including Garmin Navionics+ charts, will not share their preloaded content to networked devices unless the other devices do not have preloaded maps. For example, ECHOMAP Plus 94sv will not share preloaded BlueChart maps with an ECHOMAP UHD 73cv, preloaded with LakeVu maps. However, it will share the preloaded map with an ECHOMAP Plus 72cv, which only has a base map
Sharing supplemental Garmin Navionics+ content from a card can only be done from a chartplotter that supports Garmin Navionics+ to another chartplotter that supports Garmin Navionics+. For a list of Garmin Navionics+ compatible devices refer to the related content.
A chartplotter connected to a UHD transducer can share its sonar with a non-UHD compatible chartplotter. However, the sonar will present itself as if it were coming from a non-UHD transducer
Legacy GPSMAP devices do not share data through Marine Network with current model GPSMAP units
