Right, i know the title is a big claim, but i did get FM radio working, through SD without any extra application using a USB Fm radio. Reception was fine, even with the car moving at anything up to 80MPH, in an area where reception isnt great.
I used the Silabs USB Fm radio, with a small modification to connect it to the car aerial. Thats pretty much it! And all from a usb radio that only cost a few $!!! Couldnt get the RDS working, but not too fused about that as a trade off!
So im pretty pleased! (links to the threads to come below!)
