Product Notes
SIMRAD NSS7 EVO2 BOAT CHARTPLOTTER FISHFINDER GPS RADAR UNIT DISPLAY FOR PARTS

The Simrad NSS7 EVO2 is a used display unit that powers on and responds to button presses, but the screen isn't showing anything. It's being sold for parts, with no warranty, and returns aren't accepted. If you already own this model and need a replacement component, this could be a practical donor at a lower price. However, if you expect to navigate with it, the dead screen makes that impossible. The listing describes it as turning on but with a screen that's not usable, so it's best treated as a repair project rather than a functioning chartplotter.
GARMIN GPS MAP 8008 VOLVO PENTA TOUCH SCREEN CHARTPLOTTER 2VD000078 MARINE BOAT

The Garmin GPS MAP 8008 is a touch screen chartplotter that comes as shown and is not in original packaging. The listing highlights multiple connection points, including NMEA 2000, NMEA 0183, video, and network connections, plus engine and power connections. It also includes visible mounting holes and measures about 7.5 by 10.5 inches. Priced higher than the Simrad, this unit is described as a complete chartplotter rather than a parts item. If you're ready to install a display and want a full set of connection options, this is the one to look at.
Final Choice by Use Case
If your goal is to repair or salvage components for an existing Simrad setup, the Simrad NSS7 EVO2 at its lower price is the intended route, but only if you accept the non-functional screen. If your goal is a complete Garmin touch screen chartplotter with a variety of connections, the Garmin GPS MAP 8008 is the one to choose, even though it's the more expensive of the two.
