Head unit, gimbal mount, and screen cover. Unit works great with GPS FOR MAPPING. Would work well with auto pilot. Sonar ports stopped working so unit needs to be eterneted to another unit to read 2d , DI, and SI or etherneted to a structure scan module to read DI and SI on its own. Unit is in excellent shape.
