Hi
I got mine, loaded all the software onto the pc with all the updates, chose the kenwood firmware, said yes to all the warnings about "this firmware will not work with your head unit" (blah blah blah), let it go about its bits, stuck the dms into the phat noise, & rebooted the drive. After about 3 mins (once the lights had stopped flashing) and all done now: vw phat noise working on kenwood head unit using keg cable.
Cheers
