Compatibility / Fitment Guide
| Connection | Compatible use | Important exclusions |
|---|---|---|
| 4-pin transducer → 12-pin sounder | Compatible Garmin 4-pin transducer connected to a Garmin 12-pin sonar input that supports that transducer type | Not every 12-pin ECHOMAP/GPSMAP model supports every 4-pin transducer; check the Garmin transducer compatibility table. |
| ECHOMAP use | Selected ECHOMAP UHD, Ultra and other 12-pin sonar models where Garmin specifies 010-12718-00 | Do not infer compatibility from the ECHOMAP family name alone; rear-port configuration varies by model and generation. |
| Not compatible | 8-pin or 6-pin transducers, 4-pin power/data connectors, or 12-pin LiveScope network connections | This is not a power cable, network cable or LiveScope extension. |
Functional limit: sonar performance remains limited by the original transducer and the sounder's supported frequencies. The adapter does not turn traditional sonar into CHIRP, ClearVü, SideVü or LiveScope. Verify the exact transducer part number before purchase.

Frequently Asked Questions
Will this add SideVü or CHIRP?
No. It only adapts the connector; available sonar functions come from the transducer and sounder.
Does it connect a 4-pin power cable?
No. It is only for the transducer/sonar connection.
Can I use an 8-pin transducer?
No. Choose the Garmin adapter specifically made for 8-pin transducers.
Before ordering: compare the Garmin part number, connector pin count, keying and device documentation. Pin count alone is not a complete fitment check.
