    It may have said, “System not Installed”
    It is a friend’s car.
    When APPS button is pressed, all that happens is a message appears on screen … System Not Found
    Also Bluetooth pairing unavailable.
    And no apps nor NAV
    Radio works as do other car features.
    Any ideas what is causing this?
    Is a system reload needed or possible? if so, how do you do it?
    Is this a DVD reload or a USB
    Thanks for any suggestions from people with knowledge of this car.

    Is there a service manual available?

    There is a way to get to the MFD screen called Maintenance Mode for the Gen 3 Plugin.
    And ( possibly ) another for getting into the Gen 3 headunits info and testing screens
    I don't know if it'll work on the Gen 3 headunit, but you can try it and if it works for you that would be a great thing for us to know about.
    Turn the car On (two presses of the Start Button with foot off the brake pedal)
    Hold you finger on the Apps button
    While pressing the App button, turn the headlights on three or four times.

    To exit the headunit Info and Testing screens
    Long Press the headunit ON button
    of
    Turn the car off.

    Gen 3 might also show different Into and Testing screens while doing the same procedure as above while hold the Audio button.

    this is what the Gen 4 screens look like, I just learned about in this thread
    Retrofit Facelift Model (2015+) Head Unit to Pre-Facelift Model (2012 - 2014) | Page 2 | PriusChat
    Thanks @jacktechie

    If the head unit procedures works while in the ON mode
    It should also work when the Gen 3 is in Ready Mode.

    I think the above procedure is the one that will be the one that has the info you're looking for....

    but in case I'm wrong and the info you need for your Gen 3 is in the maintenance mode screens
    I think these instructions for getting into maintenance mode are the same for both Gen 3 and 4.


    AMD from the car car nut channel gives more info about the maintenance mode

    Yes they killed Entune in 2020 but they state the existing apps should still work fine.
    Thanks for the reply
