Hi, Next week my car will be traded in as a part-ex (for a different brand). I'd like to make sure I remove all my personal settings from the car. I think I know how to factory reset the MMI system (Settings -> Factory Reset) . That will cover all the Navigation stuff, but what about how the app is linked to the keyfob etc ? Is that done (somehow) via the app? I have the QR Code and other various details relating to the setup when I purchased the car (the dealer set things up over 4 years ago)
