This is the same as the Northstar 550i. It is a 5 inch color chartplotter with built in base maps and uses C-map NT+ for detailed charts. The GPS antenna is built into the unit, so this thing is stand alone. This unit will also take a fuel flow transducer and will give you range, MPG, GPH. It's a pretty slick unit with a beautiful display. It comes with the power and data cable, the sun cover, and an old garmin mount that I mickey moused into working for this application. I'm looking for $400 for this one.
