I just recently switched from my iPhone 4 to the Note 3. I have an aftermarket stereo in my car that I would plug my iphone into and it would stream pandora. Now, when I connect my Note 3 I get a message saying unsupported device or something along those lines. My stereo doesn't do bluetooth so I can't try that. I've just been using the port at the very bottom of the Note 3 (sorry I don't know the name, I think it is just a mini USB.) Should I try using the aux. port? Will it make a difference? Is there anything I need to do to the phone (perhaps in the settings) before it will allow it to play? Sorry it's the first Android I've ever had and I've been loving it so far but I've put a lot into my car audio and would love for it to work with my phone.
