This is great info. This is exactly the kind of stuff a geek like me has been digging deeper into resources like this one for. One question though, does this or any other radio option replace the center armrest aux input? It seems like the current iPod input has to take the place of the CD changer. This new iPod/USB adapter allows you to have both. But, does this new adapter or Sat radio or HD radio (or a combination of the 3) replace the center armrest aux input? Thanks.
