I installed on the ceiling in the center of the breeze by simply stuck between the ceiling and the lighting support my Xsara, the wire is hidden in the lining just the top of a breeze, right edge and then Completion it remains hidden in the amount goes down behind the glove box (removing 6 screws) and joined the back of my car stereo.
For the final quick installation (10min) has been completely invisible by the microphone.
I believe that the wire is 3m or + (sorry I did not notice) and decision is a jack 3.5 in all cases it is ideal.
The only minor flaw I practice a report (not important), I would have preferred a straight jack instead of an elbow termination, its daccroche can make a point further behind the radio (do not mind at all installation).
I am very satisfied with this purchase, I recommend!
