I was planning on turning my existing unit into a ice unit rather than buying a whole now shuttle. Although heavy and risky.... it would be sweet to have a 10in screen for the ice. I bought a new power cord , Ice transducer, and storage bag to make it happen. Problem I have is, the unit is a Helix 10 Si- GPS Gen 1 and this unit does not have chirp or the Ice mode that comes with the newer units. I did a software update to version 1.9 like I thought research told me to do, but still do not have Ice mode? Am I doing something wrong or does the Gen 1 just not have the option like thought? Or will just adding the transducer be good enough? Any help would be awsome! Thanks
