Is this a genuine original part?

This is a premium quality replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.

How do I know if it is compatible?

Please check the back of your GPSMAP unit. This cable is specifically for models with a 19-pin threaded connector port. It is NOT compatible with the newer 8-pin or 4-pin Garmin units.

Does this cable support sonar functions?

Yes, this 19-pin harness includes the specific conductors required for sonar signal transmission on "s" designated models (e.g., 720s, 740s).
