I currently have a 496HO with Smartcraft SC1000.

I want to upgrade to the EcoScreen with NMEA2000 capability so I can connect it to a Garmin Chartplotter like the Garmin GPSMAP 720 (https://buy.garmin.com/shop/shop.do?cID=148&pID=37719)

Here's the link to to the EcoScreen (http://northamerica.mercurymarine.co...sell-sheet.pdf)

I'm not sure which model of Smartcraft EcoScreen I need:

Troll Control 879337K51
RPM SmartTow 879338K51
SmartTow Pro 879337K52

Can't tell the difference based on the info online.

West Marine seems to sell the EcoScreen.

Is it a plug/play replacement with the SC1000?

Then I setup NMEA2000 to work with the GPS?

Thanks!

tough question?
