: Navigation's dim under 55 degrees

01-20-12, 02:50 PM
The navigation unit for my 10 sts is really dim when I start my car, around 55 degress or under. Once the interior starts warming up, the nav brightens up. I have the brightness setting on auto, and the brightness is up around 3/4 on the adjustment scale. This is my first nav, so is this normal, or is this an indication of problems to come?

You ought to see it when it's forty below zero.

LCD's are also slow to react when they're not yet 'warm'.

The colder it gets, the dimmer/slower it will be.

I noticed this with mine a a few years ago when I bought the car

It warms up and then the screen brightens up....nothing has gotten any worse over time

I have OEM navigation in both my cars, one made by Delphi and one by Denso. Both use LCD screens and both exhibit this symptom. This is quite normal. I also have not noticed any real change or progressive degredation over time.

Ok great. At least I know its normal. I just thought it might be something to keep a watch on before the warr expires. This will be interesting on the new XTS that has the lcd speedo cluster setup.

The one on my 2006 is slower to warm than the one in my wife's 2007. I figured they get slower as they age but neither one seems to have changed. Anybody had one replaced and noticed a difference in the warm-up time?
