For the most part, I love my new Galaxy Note 4. I'm unimpressed of a couple of things, though: I don't see an official "Car Dock". I have an iBolt Cardock, and when I plug it in, CarHome Ultra IS activated, but any audio is still played through the phone's speaker, and not through my car's stereo. My iBolt has a USB mini to USB/AUX split for charging and audio streaming, but I cannot get the audio in the Galaxy Note 4 to play through USB. I could do this just fine in my old phone, the DROID RAZR MAXX. What's the deal? Is there a plugin I could copy from my old phone to my new phone to bring back this functionality?
