788c Software Update and Transducer

I recently bought a new fishing boat with a 788c installed in the bow. The transducer is within the trolling motor. I updated the software per Humminbird instructions to the most recent version (4.780) this past weekend. I reset the unit, installed the upgrade, and then reset again. I cannot get downscan. Does the transducer have to be a sidescan capable transducer for this feature to be enabled? Thank You

Downimaging on a 788c

Hi wmreid: Yes the unit must be side scan capable to display downimaging. Your 788 is not a sidescanning unit, but it does utilize dual beams (200 and/or 83 kHz) and is a very decent upper end model. Unfortunately you would have to move up to the similar 798CSi to get the side scanning capabilities.
