The ISO plug from Blaupunkt is a super product: a perfect fit, build quality seems good, sound quality is very well reproduced. On my radio (Modena) playback is a little quieter than in CD or radio, but it bothers me not. I forgive only 4 stars because the connector by about 15-20 cm is too short (in my car). This means it is just enough so the handbrake (where I prefer my phone laying) and that's why I put my cell phone raising only a few cm above the handbrake (have the cable installed under the glove compartment - but> with a little more effort you can the cable Laying by the ashtray, saving these 15 cm a ...) Nevertheless, strong buy recommendation !!!
Ps: Had some trouble finding the switching function for Aux on my radio. This was exhibited in the menu. So going into the menu and look for AUX and provides this there is ON, otherwise it is not displayed in the normal shift of eg radio on CD ;-)
