    I searched a few times but wasnt able to locate this in the forums for 2017+ Prius with the tablet style display.

    ****Do not recommend making any changes or attemptong to access unless you know what you are doing, disclaiming all risk if this bricks your vehicle or display****

    Nice to be able to attain the battery status and some other goodies. I prefer the service menu because it appears to give you access to diagnosis mode while diagnosis mode does not give you access to service mode.

    Have lights set to off/DRL off

    Then>> While in accessory mode

    a) service menu
    1) press and hold home button
    2) flick lights off to tail off to tail off to tail off to tail
    3) wait few seconds

    b) diagnostic menu
    same as above except hold “menu” button with the little circles instead of home

    to exit, turn off car all the way (1 or 2 more presses of the car on/off button). I have a feeling there may be other ways to exit the service menu. Once I did this and started the car as normal, I did see a popup about “leaving service mode” or something similar on the map on the display

    Can you elaborate this a little more? Flick what lights? To what tail? Thank you!

    too bad it doesn't have the ability to disable gps entry. (like the old gen 2 early model up/down/up/down/up touch hack)

    I mean really... it lets me go in and book movie seats and get table reservations while driving, but not enter gps destination.

    (mind you i'm not advocating for doing this... I never do this myself, but if I have my wife with me it would be nice to allow her to enter).

    Just to add clarification in case the term "tail" is confusing, you can use any two positions on the stalk. Off to Auto or off to DRL or the other selections as long as you do it 4 times.

    Is it possible to turn on the video feed option via service mode? Currently we do not have the video feed option enabled for phone mirroring to work.

    No. The Navigation Receiver Assembly’s diagnostic mode is only for the navigation and rear view monitor systems; as I wrote before, it is not a general diagnostic or indicating system for the vehicle.
    The only way to enter Maintenance Mode mentioned in the Repair Manual (more info) is to use the Body Electrical > Grill Shutter > Utility > Grill Shutter Control Mode Switching function of a Toyota Techstream diagnostic system. Once the Grille Shutter System is in Maintenance Mode, driving will restore it to Normal Mode; Toyota writes, “The grille shutter control mode will be changed and initialization will be performed automatically when the vehicle speed exceeds 5 km/h (3 mph).”
