Tested on 2 cars and it works perfectly. I appreciate having the wireless connector (Iphone charge required), it can be placed or you want in the car while listening. If Iphone discharged, you use it near the cigarette lighter, it charges while you listen to music ... not bad, especially at this price!
2 points: -You Have to put up the volume side Iphone to avoid very light background noise -You Have to spend some time to find the right frequency wherever you are, at worst you can change. I remained on the 107.9 that works very well in city / highway.
