I grabbed the new update and it killed my connection to my car! I cant listen to my music or Pandora when I connect to my car stereo with a USB cable. I downloaded IOS 5 on Tuesday- no issues- car connection was fine I tried the new wireless sync with iTunes on Friday no more car connection! I think the way the iPhone connects to my pc/iTunes wirelessly to sync up, killed the wired protocols it used to connect to my stereo. I tried to connect to my wifes car and no luck there either. my stereo is the Pioneer AVH-P3200BT and my wife's 2010 G37 journey stereo , both worked fine when i connected my iPhone 4 with USB cable.
