The RXP GNS 530W/430W V2 is compatible with some of the database files included in the GTN Trainer:
- The Aviation database:
worldwide.bin for the GNS
006-d0170-00.bin for the GTN (v6.1.1 for example)
- The Base map:
bmap.bin for both trainers
Should you want to try other database files, we suggest you first make a backup of the existing files. Then you can either choose to overwrite the files, which you can restore with the backup later if needed. Otherwise, you can configure the GNS to use a different DB folder (documented in the user's manual).
