I've got a question for those who have done some stereo modding in their VX. I bought that Omnifi Rockford Fosgate DMP1 mp3 player. My question is, I'd like to pull the stock CD changer out, put this in its place and then use the stock headunit in the "CD" mode to listen to the MP3's. Is that possible? Would I need to add an FM modulator instead, or would the "CD Changer" button on the stock head unit work as an AUX port?
