The idea is actually super. Unfortunately, the sound quality is very strange, despite attempts by the equalizer. Was Getestst with an iPhone4. I have with a real radio station much better quality than with the part. But I have to say that I attach great importance to the sound. But I can imagine that some people will be dissatisfied that lay not so much emphasis on sound me. That sounds just an amateur that the sound is bad. Basses come virtually no through and if they are "dirty".
I have an FM transmitter with USB flash drive and SD card (a cheap part of China from the bay for a few euros) which has a much better sound quality. So that should be feasible in principle.
