Manual for Furuno GP-1600F

[scook]

Anybody know where I can get a manual for a Furuno GP-1600F chart plotter/FISH FINDER? Or just a copy of the fish finder/depth sounder part of the manual?

I found one for the GP-1600 (it's the same unit, but doesn't have a fish finder function) on the Furuno site. I only want to use the fish finder/depth sounder, and there are a bunch of functions I can't figure out from the really short Operator's Guide that I got off their site.

I emailed Furuno, but haven't heard anything for over a week, so they're probably not going to be much help.

Thanks - Scott
