GPS screen brightness

Hi all!
I've been trying to figure out how to dim the brightness of the screen while GPS is on. When the GPS is not running, I have it dimmed perfectly...the moment the GS comes on it is SO BRIGHT that it gets annoying driving on roads that are not lit...especially when it is raining.

I run the instrument brightness really dim. I just can't get the screen to do that while GPS is running. Any thoughts?

 

Your dealers tech specialist can do it for you or walk you through it

 

I'll have to stop in then. Shame...I just picked it up from service yesterday LOL

 

Should only take a few mins

 

Cool, thanks.
Now if I could get the darn podcasts from coming on when I hit the volume button, I'd be all set.
Too much tech. LOL
