2014 mustang. So every now and then my radio just completely shuts off and wont come back on either until next time I turn the car on or a couple days later. The screen displays nothing besides the time flickering every minute or so, also says text but no other word, and the bluetooth logo that i would assume is because my phone is still connected. Ive tried pressing every single button on the car and nothing does anything. Any ideas on what this could be?
