I wanted to use this "product" with my Blaupunkt cassette radio, which was installed in a VW. The problem is that the cable when the cassette is inserted interferes since the radio the transported cartridge down to be able to play them. but unfortunately interfere because the cable which the cassette transported each time to the top. after I had the cable fixed with adhesive tape on the cassette so that it no longer interferes. However, you have to insert the cassette with hard pressed as they would otherwise, despite fixed cable, rausflutscht again. Then came the next problem. Mono sound. At first I thought I would I interrogate. But by 6 boxes were just one kind of music on its own. Then I grabbed the radio and pressed the cartridge down. Lo and behold. It worked. Even with a good sound. Just as the sound I was out taking the finger back a little quieter. So I had to tinker a piece of paper, a pressure medium that constantly exerts pressure on the cassette me. With this construction, I was happy with the product. I'm not saying that the product is bad, just is no mention anything about it. RECOMMENDATION: FOR THE RADIOS the cassette NOT SUBMERGE MUST. Otherwise, like tinker only for people.
