Two used Garmin chartplotters sit at nearly the same price, but the right choice depends on how much risk you want to accept. Do you buy the unit that works but asks you to supply a power cord, or the cheaper one that has a sun-damaged screen and is listed as for parts? For most boaters, the working unit is the safer buy.
Quick Verdict
Pick the Garmin GPSMAP 2010 at $169.99 if you want a used chartplotter that is in working condition and includes a suncover. Pick the Garmin GPSMAP 740s at $150.00 only if you are ready for a repair project or a parts unit. It is about 12% less expensive, but it is listed as for parts or not working.
Comparison Table
| Product | Price | Price Bar | Condition | What's Included | Best For |
|---|---|---|---|---|---|
| Garmin GPSMAP 2010 Color Marine GPS Chartplotter Fishfinder MFD | $169.99 | Used | Suncover; no power cord included | Boat-ready chartplotter after adding a cable | |
| Garmin GPSMAP 740s Chartplotter Marine GPS | $150.00 | For parts or not working | Suncover and cut power cable; sun-damaged screen | Parts or repair project |
Where Each Wins
The Garmin GPSMAP 2010 wins when you need a working combined chartplotter/fishfinder display. Its product name spells out that capability, and the unit is described as working great after being used. That alone separates it from the 740s. The Garmin GPSMAP 740s wins when your budget is tight or you have a repair plan. It costs less, comes with a cut cable and suncover, and gives a tinkerer something to work with. But it is not a dependable primary navigation unit in its current condition.
Product Notes
Garmin GPSMAP 2010 Color Marine GPS Chartplotter Fishfinder MFD
This is the unit for a boater who wants a used Garmin GPS that is ready to navigate after solving the power question. It is used, works great, includes a suncover, and the product name calls out both chartplotter and fishfinder on one MFD. That combined role is a practical way to reduce the number of screens at the helm. The drawback is that no power cord is included, so your final setup cost needs to cover a cable. Because it is a used unit, give yourself time to confirm it powers up with the cable you source before you rely on it for a trip. It costs more than the 740s, but for many buyers the working condition is worth the difference.
Garmin GPSMAP 740s Chartplotter Marine GPS
The 740s is the lower-cost option and the one for buyers who see a project. The product name says TESTED, and it comes with a suncover and a cut power cable. The catch is the condition: for parts or not working, with sun damage to the screen. Even if the unit turns on, the display is risky for real navigation, and a cut power cable means you do not have a ready-made connection to power. Used with those limitations in mind, it can serve as a parts source, a repair candidate, or a way to learn how a Garmin chartplotter is put together. For primary onboard navigation, though, this is not the unit to trust.
Final Choice by Use Case
Choose the Garmin GPSMAP 2010 for dependable navigation: it is stated to work and includes a suncover. Choose the Garmin GPSMAP 740s if a lower price matters most and you are comfortable with a non-working screen and a parts-level condition.
