how do u play ur zen micro in your car?
ive tried using a fm trasmitter, but the quality wasnt great, so im looking for an alternative. u said u use a direct connection...whats that?
as for ur battery charging issue, i think i found something on ebay that might help...not sure how comfortable u are on ebay, but its a start i guess:

I connect my Zen Micro to my car audio system using direct connect. All works fine, but rather than taking it out of the car every day to recharge, I'd like to recharge the batery using a cigarette lighter adapter in the car. Does anyone know if such adapter exists and where can I find it?
