From what I know is that you still can't control the IPOD from the steering wheel with either one!

 

correct, you cant do that with either one. but with the new aai-nis 2 you are able to use the sat along with whatever u plug in to it. as for the old one u were only able to use what u plugged into it. i sure that thats the main change. do a search its been cover recently since it was just released.
