Thanks for the details mate - that should make it easier for me to get one of the ones that you've had working. Just ordered one of the ones you linked to on ebay. Have also found that logilink one easily enough and a trust one that has the same item number but looks like a newer version maybe.
When you say you copied pics to the "Dynavin side" do you mean not to Android, but into the actual radio/dvd side of the unit? What procedure did you use for that?
And if that's the case, isn't it possible it's not actually using the dongle you plugged in and is just using the parrot bluetooth module that's built in to the Dynavin Side?
It's the bluetooth Android connectivity that really is what I'm after so I can stream from phone to Android and so on.
