How to see Firmware version??

Those type things vary from one model to another, as does the software. You first need to establish what model system you have.

 

I'm still learning how Pearl S reacts to night mode, but I suspect you may have the dash lights set the same for day and night. That setting may be holding the nav. in day mode.

 

Also, if the dimmer switch is not all the way up like posted above, there is a setting that controls the Day/Night mode of the Nav.

Press the Display button and turn the headlights on. A Day Mode selection will appear with a choice for ON and OFF. I believe if you turn this to ON the Nav screen will remain in Day mode.

 

well i have 2010 prius III navi/solar package and mine didnt do it either so while i was driving on highway at night i played with some settings and it switched to night mode, so now whenever its dark and as soon as i turn the parking lights on it switched to night mode, the sensor doesnt affect but manually turning on lights tells it to switch to night mode and turning off lights all the way switch it back to day mode. if you can find some solution on how you made sensors to work please do let me know.

 

This is what it shows for my 2012, from the manual,
Depending on the position of the headlight
switch, the screen changes to day
or night mode.

YMMV different models can be different.
P.S. Go to the nav sceen, Settings, and check for day / night.

 

Yeah! I agree!

 

are you talking about that car sign on the left of eco? i dont have it either i dont know if it is the firmware difference or what

 

Well try this, press disp button and get to this screen with bars shoeing eco n power once there press trip and see if it changes n show u all those details . hope that works if not then I guess its just earlier model what's the date of manufacture on us car?

 

The little car is the EV indicator (running on the battery alone). ECO is a different throttle position to save fuel as compared to the throttle position when you push Power mode button. As Umar Ali said, the trip button displays the trip A/B information as you see it on the bottom of the pic you posted. The DISP button controls the graphic above the trip A/B information.

 

well i tried everything but i have never been able to see that little car indicator on screen when driving in ev mode eco mode or power mode. is it something with my display or what? i drove 2013 model rentals couple of times before i purchased mine and it shows car icon for ev mode as well as when you turn the car off the MID displays the mpg for the trip and some info but in my car it doesnt display that info when turn off the car it just shows time and odometer reading and thats about it. do i need some upgrading in some software or 2010 is just this way.

 

Mine is a 2013 and I have never driven a 2010 so I can't really compare the 2 different model years for the display components. I would ask the dealer's service dept.
