Keel Offset isn't Saving on a GSD 22

When using a GSD 22 remote sounder box with a compatible network chartplotter, the keel offset value may not be saved if it is changed.

The keel offset value not maintaining after being changed has been identified by Garmin as a bug and has been corrected in a software update. Before performing this update, please make sure your GSD 22 is powered on and is recognized by your Garmin Chartplotter. This update will change the software version of your GSD 22, as this is where the bug resides.
