You can only add the car to connected drive after getting a confirmation code via the car's idrive itself.
I assume that as soon as someone else adds it, it will remove the other account. I'm guessing that bit though.
Can't understand why you guys haven't removed it yourself when you traded the car in though
Standard procedure for me when trading in is to wipe all personal data and remove from Connected Drive. Just me then?
