After I had ordered a new car radio via Amazon for my Skoda Fabia JVC had to get out the old No Name Radio without USB port and MP3 playback. Unfortunately, the antenna input at the JVC radio was something different or between levels than the old radio and I did not come directly to the attachment on the interior wiring harness Fabias inside. Since I'm an absolute layman and myself never had a car radio was a let the expanded I was short a little overwhelmed with the situation. In the old Radio namely an adapter so I put already inside but deer did not come until after I had ordered it here this pull out the idea with some violence. Of course, he then fitted and the radio went smoothly. Nevertheless, I have this one installed at the end of the then arrived a day with the Post. Has thought so when then equal to the new block even if it brought no real difference at the end :-). Return would have made much sense at the price :-). Long story short. The adapter is working and the radio is playing. My new JVC Radio is the way top but that's a whole different story .....
