010-12938-00 Power/Data Cable Repalcement for Garmin EchoMAP Ultra 102sv, 106sv, 122sv, 126sv; Ultra2 10’’ Chartplotters, Ultra2 12’’ Chartplotters
Quick take
This 010-12938-00 power/data replacement cable is made for specific Garmin EchoMAP Ultra and Ultra2 10-inch and 12-inch chartplotter models. It uses a pure copper conductor, a durable plastic connector, and a rubber housing, and it’s intended for reliable power and daily use in the marine environment. The key caveat is that it only makes sense if you’re matching the right Garmin models and you’re comfortable doing the wiring.
Pros and cons
Pros
- Targeted compatibility with Garmin EchoMAP Ultra (102sv, 106sv, 122sv, 126sv) and EchoMAP Ultra2 (10” and 12” chartplotters).
- Built for durability, with pure copper wire and a rubber housing, plus an IP-68 waterproof design.
- Simple replacement goal, to swap out an old or broken power/data cable so the chartplotter can power up and be used normally.
Cons
- It’s not a universal cable, so model matching matters.
- You may need to wire it correctly (red to a switched power source, black to ground) to get proper on and off behavior.
- Some buyers note it can feel pricey compared with simpler generic cables.
What buyers think
Buyer-review evidence is relatively consistent and mainly focused on basic fit and function. Multiple shoppers report that the cable works as expected with their Garmin unit, including for typical use cases like powering the chartplotter and using it in setups where they connect the device to power for tasks such as programming or updates. Overall sentiment is positive, with a small number of comments highlighting value concerns.
What this cable is for
The 010-12938-00 is designed to replace a Garmin EchoMAP Ultra or EchoMAP Ultra2 power/data cable so your chartplotter continues to get reliable power for day-to-day operation. It’s also suited to temporary setup situations, where you connect the chartplotter to boat power to configure the device (for example, updates and programming) before reinstalling it permanently.
Compatibility and part number match
This replacement targets these chartplotter lines and sizes: Garmin EchoMAP Ultra 102sv, 106sv, 122sv, 126sv, plus EchoMAP Ultra2 10-inch and Ultra2 12-inch chartplotters. It uses a replace-part approach aimed at the Garmin part number 010-12938-00 (0101293800). If your system uses a different Garmin cable part number, this may not be the correct fit, so verifying the exact device model is the safest step before ordering.
Build and protection details that matter on a boat
For marine electronics, buyers often care less about “features” and more about whether the cable holds up to real use. This one is built around:
- Pure copper wire for strong conductivity.
- Durable connector construction using high-quality plastic.
- Rubber housing intended to resist wear and tear over time.
- IP-68 waterproof rating for added protection in wet conditions.
It’s also specified as a 10-inch cable length, so plan your routing accordingly when replacing an existing lead.
How the wiring typically works
This cable is intended to connect power and ground. The wiring notes emphasize using an ignition or manual switch for the red power wire so the unit turns on and off appropriately. In practical terms, that means you’ll want a switched positive source (red), and you’ll connect black to negative (ground). The connector is described as a locking ring style connection, tightened by turning it clockwise once you connect it to the device.
Pros and cons in plain language
Best for
- Owners of Garmin EchoMAP Ultra 102sv/106sv/122sv/126sv or EchoMAP Ultra2 10-inch and 12-inch chartplotters who need a direct replacement cable.
- Boat anglers or marine installers who value a waterproof cable design and want a connector that’s built for longevity.
- Anyone doing chartplotter setup work where the device needs reliable power during updates and configuration.
Who should avoid it
- Shoppers looking for a universal charger or generic cable, since compatibility is model-specific.
- Buyers who don’t want to handle wiring and prefer plug-and-play alternatives.
- People whose mounting or routing needs a longer run than the specified 10-inch length.
Price and availability
The listed price sits in the mid-range for Garmin-specific chartplotter accessory cables. If you’re cost-sensitive, the value question usually comes down to compatibility, build (including IP-68 and copper wire), and how much you trust the connection to remain reliable in a wet marine environment.
Alternatives to consider
If you’re not sure this exact cable is the right match, the safest alternative is not a different random cable, but rather confirming the exact Garmin cable part number required for your chartplotter model. If your priority is longer reach, look specifically for a replacement option that matches both the Garmin part number and the cable length you need for your install. If your priority is simplicity over robustness, you can also compare options that change how the device is powered, but avoid swapping to cables made for different Garmin models.
Verdict
The 010-12938-00 power/data replacement cable is a sensible purchase if you’re replacing a Garmin EchoMAP Ultra or Ultra2 cable for one of the listed model families, especially for users who want a waterproof, durable build rather than a generic lead. Just double-check your chartplotter model and be prepared for a wiring-based replacement, because that’s where most buyers’ success depends.
