Got EOL'd as they're changing BT. Come OS 3.0 launch there will be a LOT more accessories.
As for car charger - Apple's remit seems to be to do a few accessories, and then let the rest who've signed up to the "made for ipod, works with iPhone group" to do the rest.
I have a Griffin car charger that I purchased at my local Apple store, and it works just fine. I can charge my iPhone and iPod if either are getting low on battery power.
^^ Yep. I bought my Griffin one from RadioShack on clearance for $10. It's just a lighter adapter with a USB on the end of it. Then I plug in one of my hundreds of Dock Connector USB cables to it and leave it in the glove box.
But to answer the original question, no. Apple does not make one.
