Have mainly chosen here because of the Bluetooth telephony and because of the good reviews of this car radio. Bought it at an electronics hypermarket and jerk-twitch installed in a car in the 4th series of highly popular mid-size car. ISO connector problems gabs no, because even a third-party product was in there before. Radio reception is good, CDs and USB sticks it also reads a fast, AUX-in also doing well. Audio streaming via Bluetooth works well without any problems. iPod and consorts wired we have not tried it yet. The sound is above average with the standard speakers. The look is pretty with blue illuminated buttons in 2 brightness levels. The keys you meet good, they have a clear pressure point. Operation is simple and after a short reading in the manual also intuitive. Switching the source is connected to the source head, but only forward. The zapping and searching in the MP3 collections is a great feature. Handsfree Bluetooth works very simply; Only the voice of the person sitting in the car speaker is thin at the other end of the line, but at least with the window open while driving still understandable. External Microphone we have not yet tested. If you use a USB flash drive, to a very small size is recommended because a normal sized USB flash drive yet far that sticks out into the interior, and can be easily damaged.
