Navigation Screen Backlight!

Hi, the lexus is200 navigation system has this thing that the screens backlight strength goes down when you turn the headlights on. Problem is, i almost always drive with my lights on, so i can barely see the screen in the daylight. Is there a wire somewhere that i can cut so that the gps thinks the lights are always OFF?

thank you!

I am certain that through the screen options menu you can set to "day" permanently. You could on my IS's but I can't remember the exact way to set it up.

yes you can but the strength of the backlight goes down when you put the headlights on.

But i just realised if the navigation thinks the headlights are off you can't set it on nightmodus anymore.

Which kind of satnav do you have? I have the DVD satnav and mine doesn't do that. The satnav screen works independently of my headlights - even if the lights think its dark enough that the auto headlights switch on, my satnav screen will not dim until it gets darker.

Therefore, whatever state my headlights are in, the satnav screen will still only dim/brighten depending on light.

Have you possibly got something blocking the light sensor on the dash?

Hi, i have the cd-rom satnav. Don't think i have a light sensor on the dash, only infrared for the remote.

When i put the lights on the screens brightness goes down, it's really annoying in daylight.

Another thing, it seems that the satnav sometimes forgets my setting, that brightness and contrast are back at standard measures.

Click the display button on the remote it then gives you menu can't remember what it's titled by it's the option on the right change to day mode and it will stay bright all the time. :) :)

thats what i already do, but the brightness is much lower then when i put my headlights off.
