As already mentioned by previous speakers, the USB detection works very quickly.
I am particularly impressed by the Bluetooth function of the radio. The "pairing" worked right the first time without problems with my Nokia N95. The speakerphone gained thereby actually works very well. Only very rarely is one of the calling subscriber complained that he understands me only partially. But is sometimes certainly due to the strength of the cell phone reception.
Very handy, I also think the music straming via Bluetooth. The music from the mobile phone will play no discernible loss of quality over the radio.
The basic functions of the radio as the radio receiver itself and also play back CDs (belongs in my opinion almost to the basic functions;) of course the also the well-known Sony quality.
All the good features can be comfortable with the handy supplied Fernbedinung handle and round off the very positive overall impression of this device.
Here I find the price / performance ratio Top.
Absolute buy recommendation!
