I have a 2018 EX-L without nav. While driving on occasion the head blinks, goes to varying brillance going to on, scan, off at a random rate. I called the agency and they said that if I turned the car off and then on again it would reset the system. I did that, and it worked some, but it is almost like the old computer Ctl,Alt,Del approach just resetting the system but not really fixing anything. Any ideas?
