Does anyone know of an iPhone auxiliary adapter that charges the phone during playback inside your car?

I'm looking to buy an adapter to have an iPod hook-up inside my car. If I can find one that will also charge my 3GS during playback that'd be even better.

Thanks for any suggestions.

 

I use this, works great.

my pioneer charged my old iphones...says its not compatible with the 3GS...hopefully this will be fixed with 3.1...same thing happened with another OS version of the iphone on my 1st gen.

 

I've been doing some research and it appears all I need is an auxiliary adapter with a 5V USB cable thing

Scosche passPORT Charging Adapter for iPhone 3G
The Scosche passPORT allows car integration accessories that do not support USB charging to work with the iPhone 3G, fourth-generation iPod nano, and second-generation iPod touch.

 

Moogs adapter takes the cake. Looks like I just need the integration kit, and there's one for sale in the black market

 

Update:

Bought the Dice Electronics integration kit and installed it a few minutes ago. Works flawlessly... just need to get the adapter so I can charge it during playback.
