As the title suggests, I am wondering what the difference between the smartshunt and the BMV-712 is. From what I can tell, the only main difference is that the BMV has physical display that you can see. However, if I am hooking up to a cerbo GX, I can see the display there. Would this mean that a smartshunt is the better option for cerbo GX integration sine I do not need two of the same screens? Or, am I missing something in the functionality of both?
