Has anyone else noticed that the map does not have a lot of contrast? When I am driving I find it hard to read the street names or see much of the land/cityscape because the colors used on the map are so light in color, is there any way to darken these or turn on a 'night mode' like occurs on garmin units at night time, something with a higher contrast? Thanks!

Which unit do you have?  I have a x930bt and everything is quite sharp and easy to read.

I have the AVIC-850bt.  I have found the white background makes it somewhat difficult to read when the sun is glaring in the afternoon, more so than were the unit to use a darker backgroun.
