I have been able to search my iPhone phonebook in my car (a Mercedes C300) via Bluetooth till now. I installed IOS 7 and have updated it to 7.0.2 (the current build). Now when I give the verbal command "Find Name," the response is "The phonebook is empty." I deactivated my iPhone on the car and deactivated the car on the iPhone and then reconnected them. The problem persisted. Has anyone else encountered this (or a similar) issue? Any solution? Thanks.
