    Hello everyone, is there anyway to put Prius Gen 3 into Product Diagnosis Mode?

    Many thanks.

    What exactly would you like to diagnose?

    The infotainment/nav system has a built-in diagnostics mode for itself (which can also show you a couple car-related things like the 12 V battery voltage, and whether the parking brake, taillights, or backup lights are on, because those are inputs to the infotainment system).

    For diagnosing anything else about the car, Techstream software on a laptop is used.

    Thanks for the reply.

    I would like to access the 2nd hidden menu like on the Prius Gen 2,
    in order to change the country setting.
    Also, is there a way to change the temperature unit and the language?
