is there anyway to keep the nav screen in the bright mode during the nightime??

 

Just don't dim it. When the lights come on and you dim it, it goes to the black screen. The same does not happen during the day when you dim because the headlights are not on. Why would you want the bright white screen at night? It's too bright IMO.

 

This function is set in the navi options.

It's all in the navi manual.
