Apparently there is no cable that will allow me to connect my Ultrex Mega DI to my gen1 Helix 12 DI GPS. Also when looking at the Ultrex tbere isnt room on the motor to mount my XTM 9 DI 25 T trolling motor transducer due to the built in Mega DI. So do i have any options besides buying a different graph or trolling motor?
