tough googling
but here are the results:
register [http://www.anythingbutiPod.com/forum/showthread.php?p=158222|here] and download the fixup.zip (or try to find it on other pages)
read the instructions [http://www.erji.net/read.php?tid=844744|here]
but don't be scared - the page is in chinese - but the important parts are in english
you will also need the firmware for the dj
