And still no luck in getting the glideslope indicator to move from the bottom of the scale.
I am able to see the Glide Slope indicator without a problem, I'm not absolutely sure that switching the NAV Controller to MAN or STBY was the key. It could have been a coincident. Switching the NAV Controller to OFF might be an even better idea.

Did you have a similar problem when using doppler?
No. It's work correctly for me.

I always use to auto pilot controll from shift + 5. Maybe I should take a look on the forward isle panel to make sure it's coinciding correctly?
Whether I use the A/P 2D panel (shift+5) or the A/P on the Aisle Stand in the VC, doesn't make any difference mine.
