I have this connection 14 days ago Posted in my vacation, because my camera can be charged via USB and I would have had no place for the Navi. Through the USB port 2. I could use the phone also still the same. This part fits perfectly and stable on the jack, so you can rotate it, that it does not interfere with and is now permanently stuck there. Because everything turns off in my car with the ignition, I have to also worry that connected devices could "eat" my car battery one day that I would place anyway unattended there.
