I renamed the -30.bin to worldwide.bin and that worked for North America data base. I also renamed bmap.bin to basemap.bin, gns430 works with either the new baseman or the original one. Haven't done anything with the terrain or safwtaxi yet.
I just downloaded the GTN/GDU sim to get the database, but it does not have worldwide.bin but bmap.bin instead. The GNS430 install has two bin files: basemap.bin and worldwide.bin. Am I missing something?
