section is mounted upside down. Connected to the phone, the wire is in the other direction (it goes up) and clogs the "sound" buttons. I guess the whole series is mounted upside down. when we have the arrow on the top, as in the photo above cons, the connector goes to the left! I returned the 2 kits as was asked, in the envelope of my reception by writing "declined", but nothing came to them. Stay tuned. Best regards
