inicol, thanks, yes, I think someone else suggested that Kenwood unit. Personally I don't really like the look of it and think the Pioneer one looks a lot better.
I'm definitely getting the Pioneer double-din (same as Johnboy), went to a local car audio place yesterday and told them the sort of prices I've seen on the Internet, waiting for them to get back to me to see if they can get anywhere near that price. So hopefully I'll be ordering one very soon.
Will have to start sorting out prepping the fascia.
