I did a search and came up with nothing, so figured I would throw this out there. I have a 2011 Ram 1500 with the 730N NAV radio. Never had issues streaming music from my iPhone 4S until I upgraded my phone to the latest iOS 6.0.1. It's happened three times now where I start to stream, I get no sound and then the radio totally locks up. Can turn it off. Can't change the source. Nothing. I'm assuming there may be a software upgrade available from the dealer for the radio, but wanted to ask around to see if anyone has had the same issues and/or know of a fix. Thanks!
