Hi John,
Apologies your request for Route database tool was brought up a few days before the release and we were then caught up with a few issues after the new version that were priority (requests which affected more customers). We have not forgotten about your tool, Development will be able to give you more information soon.
The routes are saved in the database NavData.db3 in RadarBox 2008. The software also backsup the database itself in the data folder to prevent corruption.
