iTunes Radio Bluetooth Data

When my iPhone is connected to my car via Bluetooth to stream audio from the iPod, it displays the track information (artist, album, song) on my navigation screen.

When i'm streaming audio from the new iTunes Radio through Bluetooth to my car, it does not display the track information. Instead it displays the last song that was playing from the iPod.

Is there a fix for this? Or is there a formal way to submit a Request for Enhancement to Apple to they can correct this and allow the track info to be provided to the car via Bluetooth?
