I've had 335's with and without nav. I prefer the simpler look of the dash without nav, but do like having the features iDrive provides. For instance, having the navigation on a big screen that I can easily see is easier for me to use than fumbling with my iPhone. I have assigned the #1 radio preset button as a shortcut to turn off the screen. I don't like having the screen on unless I need it.
