BMW APPLE IPOD CABLE ADAPTER WORKS WITH USB OR AUX - eBay (item 220421906421 end time Jun-01-09 17:22:28 PDT)

Bunch more on ebay....

I question why BMW doesn't just use the USB interface and requires you to plug in the second AUX plug.....sometimes stuff in my console hits it and I get static through my IPod plus USB would carry better signal...am I missing something?
