I'm using my Ibolt Pro dock that I used my N3 with. I hated trying to connect the N3, because of the USB 3 port on it. Now much easier with the N4. I have the Usb/aux cord I never used in my car before that came with dock, because I didn't have those options on my car's stock stereo. Now just got a new one for my car and have that capability, interested to see how it sounds now, I'm sure it will sound better than just using the speaker on the phone. Haven't tried yet though. To me the IBolt docks are great.
