I have a 2017 fit that the display screen starting going nuts a few days ago. Flickering in & off. Now it’s just blank. The back up & side camera still work.
when I start the car I get a message saying my nag. System is not connected and to hold down start button for 2 second. This just turns off my car.
suggestions or use this a dealer thing?

 

My nag system was my ex wife..seriously though, is it maybe implying you hold down the power button on the head unit for 2 seconds? Just a thought…

 

Yeah, I think it means to reboot the unit. Start the car and I guess you hold down the "Vol" button on the display unit to get it to reboot. You can see if that works.

How's your battery? Are the battery connections clean?

 

yes, its the power button on the stereo you need to hold down
