When I bought my car stereo head unit I still had my 3GS & everything worked fine. It would detect my phone as an iPod & I could use the unit controls to shuffle through songs etc. I upgraded to the 4S & it still worked fine. At some point though it lost the iPod out functionality. I can put the stereo on iPod but I have to control everything with my phone. I have no clue what happened. I have the iPhone 5 now & purchased an adapter & it's the same. Anybody have a clue or had similar issues? Did a software update change something?
