iPod When did the iPod nano stop charging via aux?

(the nano or classic models)...

Hey guys,

I've gotten a new iPod every year since the iPod with video came out, and have used an iPod in the car hooked up by auxiliary since then. I moved to a nano a few years back and suddenly with that model noticed when docked in the iPod hifi speaker, or while hooked into my car, the iPod wouldn't charge anymore while plugged in...

I remember this being talked about when it happened, and vaguely remember discussion about some FireWire pin missing in the latest iPod models... Am I remembering this right?

Anyway, my point in this post is to ask if anyone remembers what the last models of iPod were that played and charged normally. I wanna go back to basics for the car and am tired of having to pull my current model nano out of the car because it dies every few days. I want to pick up a good solid "latest as possible model" ...nano or classic... that I can leave in the car and it'll stay charged up. Higher capacity would be ideal, too...

Thanks in advance for your help!

Hey Ingster, thanks for the links and info!! I didn't even think about looking for something like that. Very cool.

I think a small part of me wanted an excuse to pick up another iPod, one in higher capacity for ALL of my music to remain in the car at all times, but the bigger issue was the battery dying every few days. So this is probably the way to go.

Thanks again!
