Alpine Ida x305 or x305s

[aaronipswich]

I'm after a iPod headunit
Been looking at the alpine ida models
But not sure whether to get a older x305 or a new x305s
Can't really see much difference between the two

Any body ??? I wanna use my iPhone 4 on it

I have the 305 and it works fine with my iphone 4, great unit but the order it puts usb music in drives me mad, I need to figure out how to change it.
