I have been reading up on some of the threads about adding an aux input to our B7's and so far all the threads have been similar but not exactly like my set up. I have the 6cd changer bose system (no nav). The thread that I read seemed to indicate that I could solder two leads plus ground onto the back of my radio and have an Aux input. Can this been done (or has anyone done it and have a tutorial) for the bose system without the loss of my CD player (I don't care about SAT radio)? Also, does anyone know if the VAG codes for the Nav radio will activate the Aux on Symphony II?

Thanks
