Anyone have any experience with something like this:

I've got a Pioneer deck with a USB output. I currently have an ipod connected to the head unit via the usb cord. I'd like to plug my phone into the stereo but haven't had any luck via the mini usb on the phone, all it will do is charge the phone. I'd like to play audio from the phone to the head unit and the above cord seems like it would work but haven't seen anything like it before.

Another question I have is if there is a such thing as a usb splitter. I only have one output from the head unit but have 2 things to plug in. I think that the female ends of the usb would have to have a switch to pick which device i want to play. The ipod is permanently installed in a hidden location so it always has to be plugged in. I'd like a switchable split to bypass the ipod and use the phone, if that makes sense.

TIA
