The GSD 21 is a dual frequency/dual bandwidth, 500 W/400 W rms (dependent on transducer), analog sounder receiver, black box sounder. For new Garmin non-network chartplotters, the unit will use a CAN bus for Hyperscroll connectivity. For existing chartplotters, the unit will have a single RS-232 port for "normal" speed connectivity. Note, the dual chartplotter interface that the GSD 20 offered, will not be supported in the GSD 21 because now that Garmin Marine has a network system this feature is no longer needed in the GSD 21.
