Arliberator it seems way faster and less buggy.
that´s right, arliberator runs very smooth and fast.
my setup is HTC ONE X and iPod 4, both connected to my Appradio. With iPod/iPhone you get the original Appradio surface with optional displaying the iPod/iPhone surface. With android devices and Arliberator you get only the android surface. You have to decide for yourself which one you prefer.
Biggest disadvantage of Arliberator is that it seems (for me, arliberator forum says it should work) that it can´t use the Appradios GPS receiver. When connecting my iPod i have good signal strenght immediately, with Android it is very poor, depending on the position of my HTC in my car.
So, i am using iPod for navigation and offline music and my android for phone functions and all that needs an internet connection. mostly i have only my ipod attached because it has all the funczionallity i need
