I bought the Carenado S550 citation 2. Downloaded the latest airac cycle. No way it works with the aircraft FMS. Tried all the possible solutions, like editing the dll.xml and adding the Carenavigraph.dll. Didn't resolve.

If you guys can help me I would really appreciate, cause I don't know what else I can do.

Thanks

The problem was not the FMS but the navigraph data. For example, in a flight plan many waypoints are not accepted. How is this possible?!? I have the 1807 rev 1. Tested the same problem with my B772.

Thanks for help

Although I don’t have their Citation II, I have many other Carenado aircraft, and I have to say that the Carenado FMSs are not particularly well modelled  in terms of functionality. For this reason, like a lot of users, I tend to use the addon GTN750 modification instead of Carenado's FMS where possible. 

I know this doesn’t provide a solution to your problem, but perhaps there are some simmers out there who have persisted with using the Carenado FMS and have a bit more in-depth knowledge of its function who might be able to help you.
