Works, only on the rcd300 you need to change the connector hole. The sound is clean, fed from 5 volts taken from the Board of Radio (so as not to eat in a simple battery), turns on only when the radio is working

Everything works like a clock, the sound is excellent, the connection to the phone is instant.

So I had time to leave feedback! The goods have been bought on sale 11.11, I had in my hands already 27.11 delivery a little more than 2 weeks). I am happy with the goods, I ordered for Skoda Octavia A5, the head unit swing. After communicating with the seller, he said, that does not fit (probably had in mind the connectors of the adapter), but I still ordered it. The connector really did not fit, I had to throw out a white adapter and add a little to the farm with power (red wire "+" in the third pin, in the photo is marked with a green marker on the ejected adapter, black with a red strip on the mass under the nearest screw on the radio). Aux-adapter glued on a double-sided tape tape tape recorder on the back of the wall. I put the magnet, I run and VOA-la! Everything works! Who needs the details, on the Yu-tuba there is a video on the installation in Skoda Superb. I think to order another one in stock, in case the first failure! To the seller respect, turns the simplest magnet into a media center!)))
