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).   Disclaimer: the technical information in this post does not grant you any other right than Garmin's Trainer EULA. Please make sure you comply to the EULA prior attempting this.
