Does what is described

Have the TeckNet Universal FM transmitter now since a few days. Works straightforward: plug into the 12V socket or cigarette lighter of the car, plug in audio unit plug set (Samsung smartphone with me), empty frequency on the radio select (and best save equal to a preset button), the same frequency on the transmitter, finished ,

A minus point because without music a very slight noise is heard when playing music but not more. The transmission to the radio with me ok (cars with roof antenna on the front section of the roof), from time to time there is even a faint clicking noise or noise, as sometimes occurs when listening to the radio. Even if there is a transmitter at the frequency, the even eclipsed.

Little Wormwood tropics still: frequency response begins at 88.1 MHz and not at 87.5, but there are still plenty of free frequencies. The 12-V-connector brings the same with a USB charging socket, which is handy.

In Transmitter is also a micro-installed, so works like a headset, but I have not yet used the function.

All in all for the price surprisingly good. Far Eastern mass production makes it possible. Nevertheless, I will pass on a wired USB / SD / AUX adapter for my RD3 radio. But where this is not possible, too expensive or too time-consuming installation etc. from you a good alternative.
