I have an older car and radio has no audio jack, usb or the like. Can anyone recommend a good product to allow my HTC Desire to use the music app to play music on the radio at an acceptable standard. That is to say at a quality equal to the AM radio reception I currently experience. I hear many bagging the FM transmitters. Are there any good ones that you can recommend? In cars that have and audio jack on the radio but no bluetooth can I just use a cable to connect the phone and play music. I do not want any other capability but to play music.
