With this device, the processing is class and listen to music a pleasure. However, if you want to use this radio as a handsfree, will come with this radio in frustration. (1.Radio) ordered, delivered and installed quickly ... Music playback works flawlessly. First test the speakerphone: disillusionment. The called party hears everything choppy or too quiet. Even the (in my opinion, very complicated) manual adjustment of the microphone and the noise suppression brought no improvement. Then I searched and seen on the Internet, there is a firmware update for this radio. This should fix problems with Bluetooth. I have been playing the update and this brought only worsening. iPhone 4S (iOS 8.1) and Windows Phone 8 could be then either connect or sporadically led to the downfall of the radio. Then I complained and returned the radio. (2 Radio - Replacement) Ordered, delivered fast, installed ... Unfortunately, even with radio number 2 the same problem.
Those looking to hear a radio only for music, is well served by this. If you want a radio as Feisprechanlage should opt for another model. My choice fell on a car radio from Sony, it performs assuredly his service in our city car.
I hope my review will help the one or others in his decision.
