yes I have the Helix 9 mega and no sorry to say I don't have it figured out. map I bought with it Haven't been able to get to work. SI works and DI but with the high water the screen looks like a jungle . Bull Shoals still 22 ft above pool dropping 4 in a day. I think you kept me so busy catching fish that I wasn't able to absorb all you tried to teach me. Lol
