I recently sent my radio to Gary Tayman in Sarasota Florida. He rebuilds the radio, Now I can do Am,Fm, Usb, and Bluetooth. My car is 6 volt, Gary put a votlage converter, 6 to 12 volt. The Aurora card needs 12 volt. You send your radio to him. Turn around time was 3-4 weeks. Gary advertises in all the auto magazines like Hemmings.
Check it out! Well worth it!
