Hand held GPS

 

I know most of the topics here relate to vehicle nagigation but I was curious. Along with my c330 I have a ETrex Ledgend hand held unit. I recently comunicated with a company that has teamed up with Garmin to put out a golf distance unit. I asked them if they were developing software to download into other Garmin units. They said they were a year away, but yes they were. Does anyone out there know of any other golf GPS sofware that can be used with an ETrx unit?
