connect ipod touch (1G) and Nano (3 or 4 can't remember) to my car

hi, I got a car that has aux for the audio connector. I am trying to connect my ipod to the car so I can play it on my car stereo. I have search online and found that I can either use the following cables:

mini-stereo cable where 2 ends has the stereo cable
a mini-stereo to dock cable

I am wondering anyone has any expereince on eithe rone? Also, which one would works with all of my ipods (a touch and a nano).

I read somewhere says that newer ipod won't play music through the dock connector, is that correct?

Thanks.

so I can in fact use the min-stereo to dock then? I read it somewhere that say that it won't work with iphone but I am not sure if that would be any issue with ipod touch as they are essentially the same.

Why is apple keep chaning their design. Annoying.
