I am currently using a Pioneer FH-P800BT cd receiver and have a 250GB Western Digital hard drive hooked up to the usb port on the receiver (the HD is powered by an ipod charger). It works like a charm. I want to upgrade to a AVIC-Z110BT or a AVIC-X910BT. I know they haven't been released yet, but is it possible to use my usb setup with a AVIC receiver? Any help would be appreciated.

According to the specs that have been released by Pioneer so far, yes you can. We will know for sure when they start shipping.

Thanks for the info.
