Hi group, I'd have a goal: to stream internet audio into a car radio so I can drop a XM subscription. What is the best way as I don't have a AUX audio input. I can add a USB interface to the antenna cable as a input, or FM transmitter (tough to do as there are a lot of stations in Cincinnati) or Bluetooth stream in though a Parrot installed. If I use a USB will the audio simply go out or will I need a special app to make it work? Any input would be appreciated. If anyone needs help/advice in the Automotive area, I'd be glad to reciprocate in advice. Phil in Cincinnati.
