Thanks for the info. I just bought an iPhone 5 which shipped with iOS6.1 so I'll need to wait.
My installer was complaining about the iPhone not connecting to the unit today (X950BH). I hope he had ordered the CD-IH202 but I'm not too sure at this point. He said he's ordering another cable. I can understand AppRadio mode not working because of the firmware but not connecting at all? Picking up the car in the morning so it seems I have a lot to sort out. Hopefully a simple mistake. Anyway, thanks again for the insight on all this!
