When buying the Mega 360, you do not get a Y cable, ( have to buy it)the one for helix is the 9 M360 2 DDI Y. The one for Solix is 14 M360 2DDI Y. Also you do not get a AS GPS HS GPS heading sensor like we got when we purchased the gen1 360. You can if your trolling motor use Link if it has it for exact headings and marking waypoints. If you don’t have link on the trolling motor, then you can get one of the AS GPS HS pucks. Otherwise you can use your built in GPS of the unit you have the Mega 360 plugged into. If not using link or the AS GPS HS puck, you will maybe experience the little donuts for your boat location on your charts or maps at 0.6 or slower mph sometimes going invisible on you. It definitely gives you a more precise heading and waypoint as you create waypoints. The link and AS GPS HS will show a small boat icon on maps and on your DI SI and Mega 360 screen vs the donut.

Mega 360 comes with either a bracket to mount on Fortrex or Ultrex trolling motors. I use a Da Ducer built by Rickie of Podunk ideas.com. Cornfieldcrappiegear.com also has a custom built bracket for trolling motors, not sure of the models.
