I know 400HPA4 is trustworthy, he is all over this forum, I was just asking if anyone hod got one yet. So if I understand right with the euor nav+ you can hook up a exturnal video source like DVD or playstation, but you can't do this on a US nav+. Also on the euor nav+ you can't use AM. Is there any other big differences between the two setups. This is something I would really like to have I just want to know everything about it.
