The firmware is updated with the OS CD.
The OS CD contains firmware for many different nav systems.
The last Mk4 firmware ever release was 4-1/100, which displays as 4-1/00
The 4-1/100 firmware is found on OS CD V31 or newer (ie: any OS CD V31 or higher has the same Mk4 firmware on it)
You can get the original BMW OS here:
Home
Make a CD from the image file using ImgBurn (
The Official ImgBurn Website)
Eject map disc and insert OS CD into nav drive
Follow onscreen instructions
Remove OS CD when requested
Press the round BM button to reboot when requested
Done!
As for map discs, they can be obtained officially for your country from your local BMW dealer.
For unofficial sources, google is your friend.
