Hello how are you?
I have three problems after updating my Ford Fiesta 2016 from Sync 1.0.15139 to 3.4.21265
After the update the screen lost brightness and it does not allow me to increase it, the brightness looks normal when the engine is not running, when the engine is turned on it decreases again.
An error appears on the screen that refers to the USB ports (they have nothing plugged in).
When trying to update to Sync 3.4.22020 the update prompt is shown, but this update never starts (I waited for 40 minutes and it didn’t start).
Could you help me find a solution, I appreciate it.
