Do you have to have the radio on for the nav screen to be on. When you turn the radio off the screen goes dark and displays the time. The only way I can get the nav on is to turn on the radio and then mute the radio if I don't want to listen to it or the cd player or the hdd.

you got it bud. At least for mine which is a 2010 that's the way it is. Personally i don't have a problem with it though... turning the volume to "0" isn't a big deal.
