I reinstalled all the software and have my Lynx set as "pre" in the 740b, but still have the issue with ADSB. However, the unit now seems to be back to normal for connecting to the AP in the procedure turn. I am convinced something changed in the software with my latest map update. I thought a map update should only be that, and not slip in any other changes.
I would like for iFly to confirm there were no changes to the wireless initialization for the 740 during the map update. simple enough to confirm if this is true, correct?
