Hi, Jens, Yes, this is exactly what I was speaking of. A little clarification: The rheostat in the Falco will not adjust the brightness of the Garmin. This will only work for products like the Reality XP Garmin. For the default Garmin shipped with the Falco, SeaMax, and generics used on the C400, any brightness levels are saved just the same. Again, you'll need to make adjustments to these prior to loading a new aircraft, or by restarting sim. This is an X-Plane problem, and not something to do with our products. It goes for any aircraft using the same numbered light as the previous you had opened. If you wish, you can report your findings to Laminar and discuss it further.
