A friend of mine has a problem. Update from version 3.0.20204 to 3.4.22110 when the green screen at the end of the update appeared and while he was removing the USB, the sync showed on the screen a message that was turning off to preserve the battery. On reboot the system was up to date but there was no sound. In settings the audio button is gray, not usable. And it fails to get into the bottom left audio. Any solution to the problem?
SYNC Region: Europe
Navigation Variant: Yes
Install Type: Stock (Original Unit)
Old SYNC Version: 3.0.20204
New SYNC Version: 3.4.22110
Do you have a error message, if so what is it?
There is NO AUDIO.
To clarify the issue could be with a DTC in the ACM, by disconnecting the battery you can sometimes clear DTC’s by forcing a reset of the module, the alternative and best option right now is to check for DTC’s in ForScan or UCDS
