Garmin ECHOMAP Ultra 2 16 Chartplotter 166sv w/GN+ Mapping & GT56UHD-TM Transducer

The Garmin ECHOMAP Ultra 2 166sv bundle combines a 16-inch sunlight-readable IPS display with Garmin Navionics+ integrated mapping and an included GT56UHD-TM transducer. UHD scanning sonar, 600W CHIRP, Garmin Network ports, and NMEA 2000 provide a large complete chartplotter/fishfinder platform for offshore fishing boats and larger center consoles.

Who Is This For?

This bundle suits offshore fishing boats, larger center consoles, coastal cruisers, and multi-display helms that need a large Garmin chartplotter with the transducer included. The sunlight-readable display is useful at an exposed helm where glare can make smaller screens harder to read.

It is not ideal for a small boat or buyers who already own a compatible transducer. The 16-inch screen and network ports require more mounting space and installation planning than smaller ECHOMAP models.

Warranty & Support

Garmin provides a 2-year standard warranty. The supplied specifications do not state warranty exclusions or service procedures.

The ECHOMAP Ultra 2 166sv GT56 bundle is the complete alternative to the display-only 166sv, adding the GT56UHD-TM transducer and specified CHIRP/UHD sonar output. It also includes GN+ mapping and two Marine Network ports for a larger Garmin system. The trade-off is installation size: the 16-inch screen is excellent for offshore viewing but excessive for a compact console.
