iOS 13 Bug: Bluetooth sync of address book in BMW shows corrupt contact data

Solution:

Completely disconnect the Bluetooth connection to the car and cancel the previous pairing via the settings. Then pair the mobile phone completely new with the vehicle. In the course of the pairing a query dialog appears if you want to allow the vehicle access to the guestbook and synchronize the contacts to the vehicle. Answer this dialog with “Yes”. Afterwards the contacts should be displayed correctly again in the vehicle.
