I have my screen auto dimming set to 10 min when I have my Thunderbolt in my car cradle and charging while its in the navigation more it dims half way and when i touch the screen it goes full brightness. Is there a way to keep the screen full brightness while its charging in the cradle? and yes I have went into setting->Screen timeout->never turn off, and it still dims it after 2min or so.
 
This is a feature they added to prevent the phone from overheating. The screen dims when it thinks you won't need navigation and brightens back up when you do. The next time you are using navigation let the screen dim and don't touch it. When its time for the next turn it'll brighten.
 
I don't use a cradle, but I get the same dimming in google navigation. Is there a setting to control it? Another thing I noticed in navigation is that there used to be a seperate sound setting that was called navigation volume. Now navigation just uses the media volume setting.
