Sbingner,
If you mean the 0 disk and 1 disk was for the log files, then this makes perfect sense. As I indicated in the posts, the first was after a "create new DMS" and no music. The second was after putting some music on it.
The issue, though, is not that it won't play; it is that it does not show up on the deck. There is *no* CD Changer source available on the deck. The PB seems to boot fine, and as you said worked when I switched back to VW.
Kenwood definitely said "not compatible", not "not supported", and only applied to 2008+ decks, and only to the Phatbox/Music Keg - CD changers were not affected (what is in the PB that causes the system to break, that is not in real CD changers, I haven't a clue). I did ask Kenwood support why there would be a change, and he said "I'm not the engineer who designed it, so I don't know...". Fair enough.
I have a 2007 deck on the way (KDC-X791) - I should have it on Friday, so should post my results on Saturday. I can at least say that I did everthing I (and others) could think of to get them to talk and no go. I will be quite surprised if you find the 2008 deck to work, although I am using a US model deck, and maybe yours would be EU?
Cheers,
Jeff
