I have question for you people out there with the GROM audio interface for your P5's. Recently my 6 cd changer decided to take a sh*t so rather than spend the money on getting another one, I was thinking of just getting the GROM audio aux input. My question is, despite the changer not working, will the input interface still be able to work with the stereo? I mean it works off the MD/TAPE channel of the stock unit no?
