Ok. Right now I have an ipod, and have a cd player I'm going to put in my car to replace an older one. The cd player I have to put in has a left and right audio RCA jack like deal on the back of it. I know I could run a cord to that and put it as my aux on the cd player. But since I will be using it in my car, and possibly in friend's cars and on tour with a band, I'd really like to use an FM transmitter if possible so I can use in multiple vehicles. Anyone had any exerience with these that could possibly tell me more about if any of them are worth a crap or not. Also, are there any good car stereos out now with the ipod hook ups in the front of it?
