    Hello,
    I have 2012 Prius 3, 160k. The last few days, backup camera display/navigation display not working or only intermittently worker. Today, it just didn’t work altogether. Has been showing “system not installed “. Only regular am/fm works. Any thoughts?

    you can try disconnecting the 12v neg for a minute, but usually, you have to replace the h/u

    I agree with Bisco, time for a new unit. Mine started going weird 2 years ago.

    Thank you, that was my initial suspect. I appreciate the feedback. BTW, may I ask what H/u you replaced it with?
