Let me explain the problem....

The other day, while on my way to work, i wanted to listen to my iPod through my car stereo (alpine h/u). Anyway, on the head unit it just displayed searching.....

So i opened my glove box, and found that the base on my iPod was really warm. Since then its been dead, it wont reset, or respond to being plugged into the mac or to the charger.

The morning was quite cold, so i was just wondering if the iPod could have got wet, like condensation or something, and just shorted out?

If so, would this be something to do with the battery, or the main board?
