With a little help from Carenado support I was able to figure out where I went wrong below.2 - The AVSS will not toggle between Altitude and Ascend/Descent Modes as per the manual.The click-spot is actually on the upper part of the big outer knob, not the inner part of the smaller knob as the manual suggests.3 - NAV lights on the tip-tank version don't connect with the wingtip properly (there's a little space in between).Reply from support:"OK, that it is a problem of FSX. If you look them from the front will see them separate from the tip of the wing, but if you see them from the back, you see see them in the right position."With that it looks like I'm just down to the Adf and transponder issue.Kudos to Carenado for their multiple emails to me today helping me to figure out these issues. EXCELLENT support!Just thought I would update in case somebody else is having the same issue.Blue Skies,-Dave
