Following a two-hour journey earlier today, I proceeded to park the vehicle for a duration of 30 minutes. Subsequently, I have observed a lack of functionality in the touch pad and associated buttons, including the scroll wheels, as they are now devoid of power. Regrettably, I inadvertently turned off the head unit before to exiting the vehicle, as I was engrossed in a video on my mobile device. Consequently, I am now unable to use the reverse camera feature.
The Carplay MMI (aftermarket) was uninstalled without any impact. The wiring harness connecting the controller and the plug was examined from the bottom and found to be in satisfactory condition.
What are your opinions on the matter?
