Best car charger/player for iTouch 2G?

I'm going on a long driving vacation next week (!), and I need a car charger/player for my 2G iPod Touch. I'm assuming that these things charge through the cig lighter, but I don't know how they play through the radio. I have an am/fm radio in my Solara, a cassette player, and a CD player.

I'm a complete n00b here, any help-suggestions would be appreciated.

Mods, if this isn't the right forum, please move this thread. I thought this was the best fit.

Thanks!

Hi COSE23,
I ended up getting the griffin iTripAuto... it just arrived, and seems to be working okay. Thanks for the response.
