Bert, do you have that 1513 or 1601 DB available? I can't find the older GTN Trainer 6.1 and 6.2 will not work for me. I wish I could figure out a way to get my regular GNS 530 DB update from Garmin to work with my sim RXP GNS. I pay enough for those updates and it sure would be nice to have them in the sim. They typically go straight to the 530 datacard. I need to see if there is a way to save them and use. The <4000 runway length will not be an issue for me since I mainly use my sim for IFR practice.
