I have been looking for a way to hook up my iPod to my factory head unit. I have been researching and found a company called Peripheral Electronics. They create a gateway that allows you to hook up an iPod directly to factory head unit and browse through songs, artists, albums, etc using the buttons on the head unit. It will also charge your iPod at the same time. Anyone else heard of this? I thought it was pretty nice. I’d appreciate any feedback.
