In Europe you will find that TMC works even with the BMW CD maps, this is beacuse TMC is run as a free service and does not require codes on the map disk. In the UK the service is run by a company called ITIS, they get their income by charging more for a map disk that has the required TMC codes.

The BMW system is basically a badged VDO Dayton system, you can use the VDO Dayton map CD's in a MK III (I did when I had mine). If you go to the VDO Dayton shop http://www.vdodayton-shop.com/start....=18&ShowLand=1 (for some reason this page always comes up in German, even though the link is from the English version of the page! If you want it in English then start from the www.vdodayton-shop.com page and navigate through to the UK map disks) you will see that there are two versions of the UK/Ireland map CD, one with and one without ITIS TMS codes.
