2004 530i nav OS upgrade help!
I downloaded the v29.1.
I burned it at x1 with ImgBurn.
I opened the car door and kept it open; turn the ignition key to position 1
Waited for the main screen then removed the 2006.2 nav CD
Inserted the v29.1 CD, waited… then waited some more, it didn’t load... even thought I could hear it reading data off the CD.
Help! What am I doing wrong??
ThanksJ
