how to change display background colour mode on ncdc2013

**gsiest** · 13th May 2008, 10:03

I got a problem... I have a BC/Satnav system in my car - just like the one on the picture below (not my car on pic)

HOW can i change the display background colour?

There is a option in BC Settings menu - under display settings i think it was - to choose between Day/night/automatic mode of display colours.

If I choose the Day option - nothing happens....

Still white letters on dark background - as if in Night mode.

What else should I try? Has anyone encoutered a similar situation?

Sun is getting brighter - and it just irritates me - If I cant see whats on the radio display

I think there are 3 options, day, night and auto. have you tried them all?

**gsiest** · 13th May 2008, 15:00

yes, I've tried them all - absolutely no difference...

Does the contrast still adjust the screen or has that died too? Maybe a screen controller fault?

**gsiest** · 13th May 2008, 16:12

the contrast changes - but as i havent tried a normally functioning unit - I dont know if it is normal, or poor change...

I'd rather say - I would expect more if I change the contrast...

any more ideas?

Hmmmm no, other than try a different screen. As its an early one I don't think the two need unpairing. You should see a difference when you change the settings as you already know.

i tried to shoot a small video of the situation

my 8 megapix camera did a FINE job - and screencapture software
did the other part - but here it is

hope you can see - the Display mode - turn lighter and darker
nothing else changes on the Main screen...

Despite choosing between Automatic/Day/Night choises...

Could it be the light sensor or the signal to the HU from the lights to say they are on? maybe something like that?

**gsiest** · 13th May 2008, 17:43

well.... video was shot with headlights turned off..
when turning the headlights on - the screen dims a little - but no other change...

the sensor is the red bump on top of the dashboard?
I dont have any auto function of the headlights - hence they do not
light up automatically when it turns dark outside or I enter a tunnel
(my Peugeot 407 has this function btw)

Will Tech2 show something? what do you guys think?

If the HU gives a faulty signal to the BC or ECU unit - it should appear with Tech2?
Or will Tech2 only show major engine etc faults?
