IOS6 bluetooth connection with car stereo

Question

With my iPhone 4S running iOS5, my after-market car stereo bluetooth was able to read my song name, artist name, ect. Now that I upgraded to iOS6 my Kenwood receiver cannot read this data while connected via bluetooth. Since the data can't be read, the steering wheel control to search/skip a song forward or back also no longer works. I tested the car stereo last night with an iOS5 phone and it worked correctly, so I know the problem is related to the bluetooth iOS6.
