Hello There, Today was my CA-300, thanks to Amazon afloat. Quick unpacked it was also the first test immediately into the car. Device plug it, plug it mobile. Phone is loaded immediately. Just an x-arbitrary frequency wanted and tried. Only noise on the radio. Ok mobile to maximum volume ... Ahhh there's something. Car radio loud. Yes definitely. This is my music. Noisy, quiet, grieselig. If you move the transmitter further to the rear directional antenna it is better but never so that I would listen to music with it. Ok a couple of frequencies tested. There is simply no better. The unit is total garbage. Actually, I had hoped for radio quality (I do realize that I can so hinbekommen no CD sound). But the device can do nothing. So a lousy signal not there. My car is a Fiat Stilo 3-door. I wonder how the first in nem combination is where the antenna is even further away. 2 star there just because the good part is good as a charger and the cord can be rolled up. The FM Transmitter is a bad joke.
