Driver profiles on iDrive 7 are different from previous iDrive 6. On my Z4 M40i you need to have a different driver profile on each key and each profile needs a separate ConnectedDrive account. You can't use the same profile on two keys unless you log in each time with username and password or set up a four digit PIN code. Took me quite a while to work this one out.
You can, of course, use the Guest profile on any key without having to log in. And it remembers your settings.
