Garmin Sonar Module Compatibility

Garmin sonar modules are devices that provide sonar to chartplotters that do not have built-in sonar capability. They also provide additional sonar options that may not have been included in some chartplotters' built-in modules, such as ClearVu or SideVu.

Select a sonar module below to see which sonar modules are compatible with various chartplotters and how they connect. See the module's installation instructions for more information about network connections.
