I did not know this and frankly I am amazed. USB connectivity to put my key with my audio an audio input for connecting my iPod ... Sound just great, very present bass, commissioning very easy way: you just plug in the socket! The tuner is easily programmable by remote control, (shame the station names are not displayed) and finally the best: Bluetooth very easily associated with the tower. (Same as above, a pity that the titles are not displayed). In short, you'll understand that I'm a fan of the product, everything is quality / price. I did not test the NFC because I have no compatible device.
