I have not been getting any joy from the dealer to sort out this redness on the Navi screen.

When i startup the vehicle, the known blue navigation screen, no longer looks blue but displays with a red brightness, the setting is on Auto for night / day driving and the brightness is not even on Max.

And i'd just like to know what the Background colors on the Navi's Setup Menu does: Amber? Blue? Grey? Red?

 

that setup feature has to do with accent color when "audio" is chosen on the screen. Some folks here say it doesn't work in their TL. It works in mine....subtle, but it does change based on my choice.

Never heard of your prob before though.
