GPS Data base update
This is a two part question
Firstly, I have a a Garmin Pilot III and would like to update the data base. Is the update available online? I have a 'data link cable' but what software do I need for my PC inorder to do the update?
Secondly, what are the consequences of using an out of date data base (VFR). As far as I know the gps will be just as accurate as when I bought it for navigational purposes, presumably the only changes are to the moving map, airspace and airfield information?
