Choosing between a new, ready-to-use boat navigator and a used display sold for parts is a strange kind of face-off, but it is exactly the choice in front of you if you are shopping for marine electronics sonar navigation. The options are a brand-new Boat GPS Navigator 5in Marine GPS Navigator AIS TFT LCD Screen LED Backlight and a used SIMRAD NSS7 EVO2 BOAT CHARTPLOTTER FISHFINDER GPS RADAR UNIT DISPLAY FOR PARTS. One is intended to be installed and used; the other is intended to be pulled apart and reused. That difference matters more than any spec sheet.
Quick Verdict
If your next step is installing a working navigation screen, the Boat GPS Navigator 5in is the practical pick: it is listed as new, includes AIS, and uses a dual chart system. If your next step is repairing another Simrad NSS7 EVO2, the used Simrad unit is the practical donor: it powers on and the buttons make sounds, but the screen is not usable, so it is not a display you can navigate with on its own.

Where the Boat GPS Navigator 5in Wins
A working screen is the whole game here, and this navigator is the only one that delivers it from the start. The product title points to a 5-inch TFT LCD with LED backlight, AIS, and a marine GPS navigator design. The description adds a dual chart system with C-MAP and XINUO MAP, high-accuracy compass and GPS dual-mode positioning, and a wide DC12-36V input. If you want a new unit you can use as the main navigation display, this is the side of the comparison built for that job.
Where the Simrad NSS7 EVO2 Wins
The Simrad NSS7 EVO2 wins when the job is repair or salvage, not navigation. The title identifies it as a chartplotter/fishfinder/GPS/radar unit display, and the condition is used. The description is direct about the fault: the unit turns on and buttons make sounds, but the screen isn't usable or showing anything. That makes it a candidate for someone working on another NSS7 EVO2 who needs a donor unit to pull parts from, and the listing states no returns, so the risk stays with the buyer.
Product Notes
Boat GPS Navigator 5in with AIS

This is the unit for a buyer who wants to avoid repair work. The description calls out a 5-inch color TFT LCD with LED backlight, a dual chart system using C-MAP and XINUO MAP, and high-accuracy compass plus GPS dual-mode positioning. It also lists wide DC12-36V input, which helps if your boat's electrical system drifts outside a narrow range. The practical limitation is the price. At USD 336.52, it is the higher-cost entry in this two-option spread, so you are paying for the ready-to-use screen and the new condition. That is a fair trade when your goal is a functioning marine GPS navigator.
Simrad NSS7 EVO2 (for parts)

If you already have a Simrad NSS7 EVO2 with a damaged screen, this used display is the reason to consider the parts route. The unit powers on, and the buttons make sounds, but the screen is not usable or showing anything, so the description positions it squarely as a parts source. It is a used Simrad NSS7 EVO2 chartplotter/fishfinder/GPS/radar unit display with no warranty, and the listing says no returns. That combination of condition and restriction is the real trade-off: the lower price buys you a donor, not a display you can navigate with. If you need a screen to use, this is not the one.
Final Choice by Use Case
Pick the Boat GPS Navigator 5in with AIS if you need a new, working navigation screen and want features like AIS and a dual chart system ready from the start. Pick the Simrad NSS7 EVO2 for parts if you are repairing another NSS7 EVO2, already have a working display elsewhere, and need a donor unit for components. Both options are legitimate, but they serve completely different days on the boat.
