Getting all my stuff together to mount my 360 and the end of transducer cable does not match the depth finder. One on 360 is round and one on unit is square. What the heck. Do I have to buy the splitter cable that I see for $54.00. My unit is supposed to be a gn3 mega + and serial number is 20010902-0249. Thanks Don
Disregard this post I figured it out. I had a 75 year old brain fart.
