Guys thanks for the comments.
All items are being looked at by service at the moment. They now have details on the towbar also finally.. Guys at Chatswood were helpful (thanks for the tip)
Yes they know about a few of them already, sub woofer - polarity problem, FM stations. The DVD issue is a new one though. There is an option for an inline antenna connection which should have been fitted. I'm not happy with the units headrests or integration just yet though...
Good bunch of blokes down there....
Gotta admit I left about an inch of petrol in the tank when I dropped it off at about 5:30

, the low petrol chime scared the life out of me!!. Glad service is next to a petrol station.
