I have an '05 Sundancer with 8.1 Horizons and the Smartcraft system. I have been replacing all of my outdated electronics and have started to think about replacing the monochrome old Smartcraft with the new Vessel View 7. Does anyone know if it is compatible, i.e., simple plug in to replace or can be somehow "made" compatible, with my '05 engines and systems? The Mercury website says it is compatible with "Gen II" engines '07 and newer. That would seem to me that I may be out of luck, but I pay for anything to be done with electronics as I am clueless in this area.
