Figure i should update this since i have the Appradio2 installed.
I installed appliberator on my Note2, and its been awesome. Sometimes takes a minute or two to connect, but otherwise a great solution for those of us who really want a customizable experience. I just did a 4 hour drive, had netflix going the whole time (for the passengers of course).
While I was at it, I replaced all the speakers with a full alpine setup, i ran the RCAs to the amps, then used the RCA out on the 4ch amp to chain into another amp for the subs. I also grabbed the radio controls from the column of a SVT focus and modded it into the steering wheel column, so now i have volume and track controls at the tips of my fingers (see 3rd pic).
Im quite pleased with the setup. Here are some pics (dont worry, the car and cables got cleaned up)
