I have a HELIX 12 CHIRP DI GPS G2N that is using a XTM 9 WIDE DI 20 T - Trolling Motor Wide DualBeam Down Imaging Transducer. Without resetting to the factory defaults what is the default connected transducer setting? I'm trying to get the down imaging to actually show a image I can interpret while also using the 2D sonar for vertical fishing.
