Works, no humming

Really very strange, however, is the length division. The developer has simply not considered that the USB connector and the AUX-In in the vehicle in the most likely? most cases are not further apart than 30-40 cm. This cable could be from the division, bridge the huge distance of about 1.20 m between the said vehicle connections ...
This sub-optimal length division causes the cable division takes place (in USB and jack) far before Armauflagekasten. In the box are in my car the appropriate car ports for USB and AUX-In; and of course many utensils.
So then two cables snaking funny (after graduation) in a large part to the automatic lever up into said box.
Mostly I get the box (the more often and is to made) then only with difficulty, because always one likes :-) "invests" of the two cables to the closure of the box. A single cable would very probably easier in everyday to get to grips with as two ...

Therefore, there is therefore a point deduction; as I said technically the cable works for me.
The total length of the cable is approximately 1.20 m; So try before whether it is enough.
