Does anyone know how to wire up 2 stereos in the CRX? I have a Sony Xplod right now, which I like a lot, but it's a CD player/radio and I want to use my mp3 player. It has an auxillary port that takes RCA cables for a MD changer, but to use it the stereo requires a controller cable (Sony Proprietary) to let the head talk to the MD unit. Even if I had the cable, I don't think it would work. I looked into it a while back, but couldn't find anything. Anyway, so I still have a stock Acura stereo that came with my car, which is a tape deck. I can use my mp3 player with that using a casette adapter. I'm sick of carrying 20 CDs around all the time, I'm going to switch to the Acura deck this week and see how I like it. What I would really like to do is keep the Sony in there, and then mount the Acura deck behind the console with the wire coming out for my mp3 player, and have some kind of switch between them. Anybody know how to do this?
