[ref]Dr. Zed[/ref], Just PM me if you want to talk through it, it's not that bad when you know how each of the options work. All the hassle is worth it for Bluetooth and phone connectivity in my view, it will sound better as well, even if you don't change the speakers.

Thanks mate, appreciate that. I'm looking for Bluetooth mainly. I found the stubby aerial to be rubbish at picking up reception so would rather just listen to my own music anyway.
There are so many options, I really thought it would just be a case of buying the fascia and be done with it. Guess I was wrong huh?! I'm also very worried about the colour being completely mismatched.
So based on recommendations I now have these in mind:

The first one comes with the wiring etc, whereas the second one doesn't. I'm assuming I'll need all the wiring bits for the aerial etc so I can still listen to the radio if I wished...
