If you are connecting a transducer that was not included with the chartplotter, you may need to set the transducer type to make the sonar function properly. If the device automatically detected your transducer, this option does not appear.

This chartplotter is compatible with the Garmin ClearVü™ transducer as well as a range of accessory transducers including Garmin^® GT transducers, which are available at www.garmin.com.
