I have a v28 (soon to be v29.1) Mk4 DVD system in my 2003 Mini Cooper S and an old old old (2003) DVD in it. I've bought an original 2007.1 Road Map Europe Professional disk which just doesn't work. The error message is:

"Incorrect CD/DVD in navigation computer, Please insert appropriate CD/DVD"

Any ideas? I can read the DVD in my laptop.

Thanks in advance,

Mike
