I just upgraded my console unit to a 1199, and moved my 998 to the trolling motor on a HDSI transducer. Problem when I switched out a older 798 SI without a GPS for a 798HDSI I lost the US2 sonar option, I only have now quad beam, and compact sidescan. I have quad beam selected for now ? is this going to be a issue with using the US2 in my minnkota 101? I don't want to do any damage or loose any performance. Appreciate any advice or experiences.
