I am more than satisfied with the Sony MEXBT3900U car radio. It has a very good and clean sound. But you can adjust the sound even further. In conjunction with a good conditioning in the car can thus get a lot out. The Bluethoot functions are very useful. The speakerphone and the ability to stream music from your phone via Bluethoot if I once lost my USB stick, I use most frequently. The included remote control I use less. But it is necessary to get into the deeper menu structure and the other functions to adjust. In its entirety, a very good value for money.
