Upgrade Navigation Software 2001 540i

[sunsetter70]

Hi,

I would like to upgrade my navigation software to get the split screen and hopefully or maybe the BMW background screen when you open the door and the screen illuminates. I have some information of upgrading my MKIII to version 5.0 (V.19), but for that I need the part number 65 90 0 140 531 that has a key that comes with it. I would like to upgrade it to the new version 22 if possible. Can some tell me if I have to upgrade it to V.19 with the key first and than do the V22 or can I just upgrade it using the V.22 CD?

Thanks,
