I downloaded V29.1 and burned it to a CD with IMGBurn 2X with verify. I unpzipped the files with WinZip. Upon installing the CD into the Nav system on my 2001 M5, the screen went blank. I am sure I did something wrong but can't figure it out.
When installing the CD into the Nav system, do you have the key on/off. What is the actual process one should go through to make that happen correctly.
Thanks for the help!
