I have a 2018 Maxima and the last few mornings my stereo fails to start. I get the Nissan logo but then screen just stays blank, no main screen or back up camera. I have restarted car multiple times and this does not fix the issue. Later in the day the stereo appears to be fine. Seems to be temperature related (50 degrees typical morning right now). Any ideas? I'm assuming something related to circuitry in the unit.

 

Sounds like a replacement radio is in your future,
