Sync 4 upgrade

I recently installed this screen from here and I got it all set up with the majority of everything working except the following;

  • Volume knob on the screen only displays 0 no matter what volume I set it too.
  • HVAC controls only work with the OEM controller plugged in.
  • HVAC controls on the screen can only activate the fan but not control the speed of the fan.
  • Fordpass doesn’t seem to work.

I have Forscan and any help would be greatly appreciated!
