This adapter does not work on my car radio. I have a clio 2 2001, and the car radio is the original one. To not make the same mistake as me, make sure your car radio does not have the auto-reverse function, or if this is the case, you can disable it (which is not possible on my own). Because of the auto-reverse, the player and the cassette packs idles. It is also stated on the package adapter that this situation may occur.
