Thanks for the information. I did stumble across that thread before but it didn’t give me enough information. I wrote to the poster who said he could provide that info and I’m waiting for a reply.
I need to use RealityXP because I’m using it to study the GNS530 for real world flying so Navigraph is out.
Can anyone tell me how to update the RealityXP database with a new one from Garmin? I know that I would need to buy a subscription from Garmin but I don’t want to spend the money before I know I can actually install it.
