Right now I am using an x940bt but love the way the appradio 2 works with the ARLiberator and my Galaxy S III. I am just wondering if anyone has had experience with both units and has any input for me as to whether or not I should consider this move and pros/cons of doing so.

I haven't used the x940bt, but I have used several other avic models in the past before getting the SPH-DA100. I really like the appradio2 features with ARLiberator. Google nav with traffic is a great option. Ultimately I like the freedom of using whatever I want to use to display on my system.

For me the only pitfall is that I have an older tv in the back for kids, and the Appradio2 doesn't have outputs to go to the tv like many other pioneer units do.

I see. Good info there. The outputs don't concern me too much because my car is only a 2 seater.
