If you are shopping for marine electronics for sonar navigation, the first fork is whether you want a dedicated color chartplotter with fishfinding or a Garmin navigator that also handles land routing. Both of these used Garmin units are viable, but they point in different directions. The price gap between them is USD 70.09, which is enough to matter once you factor in wiring and accessories.
Quick Verdict
The Garmin GPSMAP 2010 better fits a boater who wants the combined color navigation and fishfinder experience. The Garmin GPSMAP 478 better fits a boater who wants marine and land navigation for less, with the understanding that cables and chargers are not called out as included.

Product Notes
Garmin GPSMAP 2010
The Garmin GPSMAP 2010 makes the case for a dedicated color display. It is the higher-priced unit here, and the color marine GPS chart plotter fishfinder MFD is the centerpiece: you get navigation and sonar viewing in one screen, with a suncover included. The trade-off is that no power cord is included, so you will need to add a power cord before the unit can operate. This is a used Garmin made in Taiwan, so it should be treated as a pre-owned component rather than as a fresh unit. If your priority is a color all-in-one display with fishfinding, this is the one.
Garmin GPSMAP 478
The Garmin GPSMAP 478 takes a different approach by combining marine and land navigation in a chartplotter receiver. It is the lower-priced option, and it offers Garmin's navigation capability plus the flexibility to move between water and road use. The unit has been fully tested and is described as being in great working condition, which is helpful for a used receiver. The limitation is that cables, adapters, and chargers are not indicated as included, so you may need to source those separately. At its price point, the 478 is best for a boater who wants both marine and land navigation without paying for the color all-in-one display they may not need.
Final Choice by Use Case
If your use case is primarily fishing and you want a color display that can show sonar returns while you navigate, the Garmin GPSMAP 2010 is the one to buy. If your use case is a mix of boating and road travel, and you want to spend USD 70.09 less, the Garmin GPSMAP 478 is the sensible pick. Both are used Garmin chartplotters, so the final decision comes down to whether you value an all-in-one color fishfinder MFD or the flexibility of marine and land navigation.
