Thanks for all the info. I have read some additional material and I have a couple of question. I have an MKIII, CD. What is the latest OS upgrade version that I can aim for? Some the information posted here suggests that v.23 is the highest you can get if you have an MKIII. I found this link with different file version http://www.e38.org/nav/ . Now the million dollar question, what files do I need to burn from this list to succesfully update the OS of my 2001 X5?
thank you guys!
