If we can get back on topic hear. The D3 is three + year old technology and is not expected to maintain complete compatibility with current technology. The solution is simple. If you want your iPhone to charge, upgrade to a unit that supports that feature. Enough said.

I ended up running into this problem in the beginning of the year when I purchased a 4th gen ipod nano upgrading from the 2 gen which I using. Here is my post and the information which I got.

I was going to get the Scosche passport and see if it worked but I ended up calling their tech support and they informed me that it is not compatible with the pioneer units using the CD-i200 ipod cable.

I ended up returning the 4th gen nano and bought a used 2 gen from ebay.
