Can the D3 be in split mode in any way? I know it can't for rear view, but like radio split with map. Kind of like when the unit is "off" it shows direction and turns in the right hand side. Can't figure out if I can do this while other things are functioning. Hope this makes sense. Thanks

no it cant do that. THe Z1/2 cant do what you are asking either, but it does have dual spilt screens for other things.

If you hit the 'hide' button on most sources, it will remove most of the information on the screen and display those arrows telling you your next turn or two on the right side of the screen. I think that is what you are referring too. Leaves a lot of the screen blank, but i guess that would be okay if you have a cool background
