You mean to tell me the Helix 10 Mega SI, DI G2N will not share the mapping data from the card that is in the unit with the other Helix Mega 10 G2N?
So.... you have to buy TWO Lakevu maps if you want both units to share the same graphing information?
So.... You have to buy TWO AutoChart Zero lines if you want the front unit to have the same countour lines you are mapping with the front fish finder?
So.... If we are mapping the lake on the Helm, that newly created map wont be visible on our front unit?
How else are you supposed to navigate using the front unit when using the trolling motor?
Please tell me I am wrong.... or the Humminbird website is wrong?!?!
