For a long time I wanted to connect my iPod or other audio source to my car stereo. Not wishing to go on too expensive equipment, I tested several FM transmitters. But we quickly discover the limitations of this type of device. This interface fully meet my expectations. Super simple installation (the hard part is finding where to route the cable for a clean thing). It worked the first time. The sound is surprisingly good (but not tested in all conditions of travel of the vehicle) You can spend tracks via satellite. No complaints. Located on Scenic 2 radio list with tuner and navigation system.
