Hello all.  Hopefully I am in the right spot.  When I power up the Fenix, Power and Batteries, the screens do not work.  Nothing comes up, MFD's radio stacks, nothing.   I have the v2.2.0.334 version. 

Sounds like the FenixSim A320 App isn't starting to check if the Fenix is a legit copy - do you get this App momentarily flash on the MSFS screen just before your selected departure airport is loaded? if not, start the FenixSim A320 app manually and it should work. A few versions back I had to start this manually everytime. Another problem could be that 3rd party Fenix liveries aren't compatible with the Fenix B2 update, I had this problem in the past which caused similar symptoms to yours mentioned

Hope this helps.
