Let me state from the start that I'm a theologian by trade- so most of this stuff is a bit out of reach for me. As I understand it- from reading the forums- the iphone is not able to be used to do tomtom traffic, etc- but can do hands free on some of the units. With Apple releasing the software developers kit for the iphone could any of that change, or is it a hardware/hard-wired issue that is not likely to resolve at all?
