Can't get Down Imaging on my 798

I have a Humminbird Model # 798 ci SI and I can't figure out how to get to the Down Imaging screen. I have scrolled thru all the views, but no Down Imaging shows up. Any ideas ? Thanks

Make sure the down imaging view isn't marked 'hidden" in the menu. Also, depending on how old the unit is, it may have never had the down imaging update done.

Shellback has good ideas there!

I think Shellback is right. The Down Imaging sonar addition did not happen until software version 4.780 (about January 2010). If your 798ci Si is running software older than that you will have to update it to get it.
