Hi,
I have a 2002 X5 and navigation MK3.soft 3-1-30,
I would like to update 3-1-63.
There is a problem. Navigation unit does not take any OS CD. I tried various burning software, the CDs, I have about 15 CD with OS. I insert the CD in navi appears on the screen "software wird geladen" and that's it.
According to different views on this forum I assume that flash memory is damaged.
Please help,: where the motherboard flash memory is stored? I have a another MK3 damaged and I tried to replace them.

Thank you for helping
