I have a problem with my homecockpit. I know that the CS767 uses the standard FSUIPC Offset (0x0C4E) for the course of Nav1. I can read this offset correct and show it on my 7-segment displays in my homecockpit.

But when I turn the Knob for the course in my homecockpit, the course on my 7-segmnent displays increases (or decreases), then I write the new course to offset 0x0C4E. But the course in the CS767 doesn't change. If I use the log of FSUIPC, I can see that the writing to the offset 0x0C4E is succesful. But why doesn't it show up in the CS767 nav radio?

I already did try the Lvar, but that one is also only readable and not writable.
