CoolP,

Thanks for the answer. That makes sence indeed.

But now one more big problem.

If i change to HDG mode to update the INS1 it doesnt update at all.

I follow the manual and have watched the video tutorial about 10 times now.
But the update light does not light up at all. do you know if there is a special setting in the 707 to do because i think it has something to do with the nav1 / nav2 freq active status.

Kindly regards,

Rick Winkelman
