The transfer works as far as possible properly. Only when you are traveling in the forest or mountainous areas, and this seemingly radio frequencies change to decimals, it is occasional disturbances. Nevertheless, I would usually give five stars, but a shortage is extreme, namely the supplied jack cable. This was from the beginning a kind of loose contact. Then I ordered a deleyCON PREMIUM jack cable. This now also works to connect the phone to the transmitter properly.
Therefore, there is only 4 stars.
