Looking for the BMW Sat nav files

Hi guys,

Im looking to download the software which is used on the BMW "08" Plate Tourer model (Im rubbish with the models on BMW's). Was wondering if anyone has a link or an up to date version which I can download ideally with the speed cameras. As I understand it there are different versions for the different cars and depending on the year you have you can get different revisions of the software - or am I barking up the wrong tree?

Thanks
