I've noticed in the daytime that the navigation screen is very dim. It used to be bright enough to read in the sunlight, now it's hard to read with even a slight reflection. Is this a known problem?

 

Has someone been playing with your screen brightness/contrast controls?

 

Some people have complained about the nav screen in direct sunlight. The RDX's screen definitely isn't as bright as those found in other cars (even the old MDX). I've found it pretty good in most cases...the only exception is in direct sunlight it is pretty hard to read, but not totally unusable.
