I'm having a little trouble finding how many USB outputs the Avic z120bt has.

Basically, my goal is to be able to run separate cables for my iphone and flash drive. The iphone cable would be mounted near the shifter so it's easy for me to plug it in when I get in the car, and the USB drive would be mounted in a cubby where it could stay more permanently since I won't be removing that very often.

So, is this possible? If so which cables do I need for it? I know I obviously need the ipod cable, but do I need a proprietary USB cable to or would I just use a regular USB cable?

It has only one USB port. U could put a splitter but I think only one has to be connected at the same time which could be a pain.
