I’ve the latest Sync 3.4 build 23188.
Initially updated using ford direct usb update.
Tried master reset.
Also updated using automatic Cyanlabs update, followed by master reset.
Note: I use ford navigation and subscription to live traffic.
I’ve tried rsetting both ACM and APIM using forscan, but have not updated the core firmware/calibration.
Battery is good, and reset oftern occurs after driving a few minutes, and voltage on system is 14.6v.
Typically radio sound goes off, and next press of button most presets disapear. Occasionally complete system looses everything like a master reset.
What would you suggest as next step? Complete reformat and reinstall? Or downgrade, and stay on older version?
