I'm sorry but I think you are wrong. You can check in the link below:
http://104.171.4.62:8800/Download/Veh/MaxiSYS/Bmw/en_about.pdf
BMW V 7.00
But even if you don't do it with Maxisys, you can connect Maxiflash Pro to your laptop and do it by the BMW OEM website.
If you need I can give you the link, just inform if you live in Europe or America, because they are different.
