When I bought my center console it had 2 crappy 5"s at both places. I replaced the console with a Helix 998 C SI, and finally my front 5" died. I can get an 898 C SI for the front for about $400 or could get a new network capable Helix 7 DI for $600. As I haven't had SI at the front, do people really use the SI capabilities at the front? Or does turning the trolling motor kind of make this hard. Other thing I like about my 998 is it has 3 presets. Wondering how much better the newer models DI is over 6 year old technology in the 898.
