None of Garmin's other divisions seem to be interested. Although you might send them a suggestion at this link Submit Ideas to Garmin. For the most part this site is a user forum. We don't really know if Garmin mines this site for suggestions and gripes.
Another good site for questions about Garmins other products is found here --> http://forums.gpsreview.net/ Though they don't have a dedicated on the water forum either.
