I've started looking into this. See this thread: OEM CD changer from 2007
I'd be surprised if Subaru doesn't sell the interconnect cable as a replacement part. That would get you the connector that plugs into the rear of the factory HU. Subaru might only sell it packaged with the "ashtray box" but you could probably cannibalize that for the 3.5mm jack.
I'll update my FAQ thread when I find out more.
