PT If it's supported by EasyGPS (http://www.easygps.com/) or
PT GPSBabel (http://www.gpsbabel.org/)[1], then you can generate
PT a better database of airports at my site
PT http://navaid.com/GPX/ and load it into your GPS.

This is a great database which I've used for an older non-aviation GPS
I keep as a backup unit. Paul, thanks much for keeping this going.
