Welcome to the forum mate
As Ben said, there is a huge amount of info and hot tips contained within. Dont be shy in raising a question or chiming in on another thread.
I have an 09 D40 2.5 Titanium.
Mind you I don't what is special with the titanium as all it has is Bluetooth and even that isn't great.
I bought it as a tow vehicle for my van and it does do it well.
The 2009 Titanium is just like my STX except it has fancy roof bars, leather seats, Parrot Bluetooth and (the most expensive bit) a nice chrome-plated "TITANIUM" badge on the tailgate. Otherwise it's an STX dual cab - that should help if you're looking for advice or manuals or parts.
