After I (as the supplied interface cable from Mercedes is not long enough) have tried two extension cables for the price of 10 or 15 euros, both did not meet their intended function, I thought with this very expensive product finally the goal to achieve, namely the interface cable from the center console to the dashboard, on which hangs the i-Phone to extend. Far from it ... :-( The connectors on the cable are sitting on both sides very loose, the audio transmission work by sporadic and the charging function not. Conclusion: Good quality and reasonable price have nothing to do with this product.
