How does the transfer of my data to third parties via BMW CarData work?

A telematics-compatible BMW vehicle sends specific telematics data to BMW within a valid BMW ConnectedDrive account, subject to service use and availability. This data will be stored on a BMW server. BMW CarData offers BMW customers the option of seeing their currently stored data at any time. Third parties in turn can access selected telematics data in order to offer you personalized services - provided that you explicitly direct BMW to release this data to this third party.
