Does anyone know the difference between CD-IV202 & CD-IV202?  Both are to add video for AppRadio mode on an Iphone 5.  Both require a VGA-to-Lightning adapter...  Do they work interchangeably?

I have a AVH-X3600BHS and honestly can't tell the difference or which one to buy.

I believe it is the 203 based on the manual. Im still waiting for my cable before I can test mine out. I also have the 3600bhs.
