Dietz Ipod Interface install problem



I bought this on ebay, did the install as per instructions, but, when I select it on the radio, it just says "Loading", have checked all the cables and connections, everything is as per instructions, but it still doesn't work.
Anybody has any experience installing this?, any advise?
