Thanks for all the responses guys. I have decided Im going to get one of Demon666's glovebox MDI kits in a week or so's time (provided he has some left). 
I do have a question - When installed am I able to change the interface cable easily? or do I have to go ripping out the dash and changing it back there? 
I would like the IPOD lead, and definately a USB lead and possible an 3.5mm lead like Furby has linked to above. 
Thanks,
Faz
