Lowrance ifinder h20c question

Does anybody know how to enter gps coordinates on the lowrance ifinder h20c? Not sure if it is possible.

Thanks for any help.

I've owned the unit, as well as an original Ifinder. I really never figured it out myself. I would manually place the cursor at the Lat and Long then mark it as a waypoint. It's time consuming, but you can mark several in an area you plan to fish the night before.

Yes it's possible... http://www.lowrance.com/upload/Lowra...811_101805.pdf
