Where do I plug in?!

[kop44]

Hi there,

I am a relatively new ipod user, and also bought an itrip. I am less than impressed with the itrip, as I often find it very difficult here in the UK to get it sounding decent on a frequency - and then it tunes out almost as soon as I drive anywhere.

I am therefore hoping to find a gizmo that allows me to plug into my car radio, and play my ipod tunes, without relying on any radio signals.

I have already looked at the accessories, but didn't really understand how they worked.

Where would the ipod plug into my car CD player?
What would people recommend me to buy?

Thanks in advance.
Paul.
