Im not sure that the actual name is, but wanting the Mercury "brain" box to interpret info to my Lowrance Unit. I have the smart gauges on the dash but really want it for using this screen when testing props etc...having all that info right in front of me and not having to look at 2 or 3 places would be nice. Mine is a 2015 300Xs withe DBR kit and the current dash unit is a HDS12 G3 but swapping to a new Carbon 12...The only thing that does not work on my dash is the speed since the 300 does not have in it, but they are not accurate anways and I always use GPS....With this set up, I guess the speed would show on here from the built in GPS in my unit? I take it since I have 2 units connected already with NMEA I would need to install a "T"?
