Calls work fine when paired to my Kenwood Excelon DNX6990HD but music controls through Bluetooth is not fully functional. I can make and answer calls on the on screen display on the Kenwood, but when it comes to music, there is no Track Info, and I can't skip, pause, play, or use any of the onscreen controls! When I use my iPhone 4S with iOS6, I have no problems. Hopefully Kenwood will come out with an update. It's really frustrating since I have to wait and pay for the $30 adaptor to use in my car and now I'm not certain if I'm going to run into the same issue.
