During a telephone conversation, the unit my call lists simply read from WIN8 Phone and the quality very good, it can still be adjusted individually here. The supplied microphone was put sticks in the wheel, but it may be the long cable Duch sat down in almost every corner of the car.
The menu navigation on the radio is rather intuitive, you can adjust without much manual already. In any case, reference should be made to the Service Instructions for installation necessarily, because I had to, for example, installing a Antennenadaper with built-in amplifier, since the original antenna cable did not have the necessary antenna connector. And this gets happens to be the feed from the radio.
Tip If a new framework is due: I had to install a new framework for radio anyway, I did not di screws from the DIN-frame solved. So I can not just take out the device with the supplied hook, but it has such unscrew the original radio. But it is fastened securely in the car.
Conclusion: Anyone who buys this device certainly makes no mistake, the opposite here you get a lot for relatively little money.
