When you're shopping for marine electronics sonar navigation, the toughest call is often whether to buy a new unit with extra features or a used one from a brand you already trust. That's exactly the trade-off here: a new 5-inch Boat GPS Navigator with AIS and dual charts for $336.52, versus a used Garmin GPSMAP 2010 color chartplotter/fishfinder for $169.99.
Quick verdict
If your priority is the lowest price and you want a Garmin-branded color chartplotter/fishfinder, choose the Garmin GPSMAP 2010. If instead you want new hardware, a 5-inch backlit screen, AIS listed in the title, and dual chart systems, the Boat GPS Navigator 5in is the unit to get.

Where each option wins
The Boat GPS Navigator 5in wins for boaters who want a new unit with a 5-inch TFT screen and LED backlight. It also stands out with a dual chart system (C-MAP and XINUO MAP), AIS in the title, and wide-voltage DC input from 12-36V. If you need speed and heading from a compass/GPS combo, this one is built around that.
The Garmin GPSMAP 2010 wins for budget-focused shoppers who want a color chartplotter that also works as a fishfinder. It's used, but the seller reports it works great and includes a suncover. The missing power cord is a real consideration, though.
Product notes
Boat GPS Navigator 5in Marine GPS Navigator AIS TFT LCD Screen LED Backlight

This new unit takes the feature-first approach. Its 5-inch TFT LCD uses an LED backlight and 480 x 272 resolution, and the dual-mode positioning combines a compass and GPS for speed and heading. The dual chart system lets you switch between C-MAP and XINUO MAP depending on your waterway, and the wide-voltage design handles DC12-36V. The main drawback is the higher price compared to the Garmin; for that money, you're paying for new condition, the 5-inch screen, and AIS listed in the title. If those features matter, this is the easy pick.
GARMIN GPSMAP 2010 COLOR MARINE GPS CHART PLOTTER FISHFINDER MFD With Suncover

This is the lower-priced choice in this head-to-head. At $169.99, it's about $166 less than the Boat GPS Navigator, and you get a Garmin-branded unit that combines color chartplotting with fishfinder functionality. It's used, but the seller says it works great, and the included suncover helps protect the display. The biggest limitation is the missing power cord - you'll need to buy one before you can power it up. You also give up the dual chart system and AIS features found on the new unit. If you don't need those extras and you're comfortable with used gear, this Garmin delivers the core navigation and fishfinding experience for less.
Final choice by use case
If you want to spend the least and don't mind a used Garmin chartplotter/fishfinder, the Garmin GPSMAP 2010 is your pick. If you're willing to pay the higher price for a new, 5-inch screen with AIS listed in the title and dual chart support, the Boat GPS Navigator 5in is the right choice.
