Pros: I like. Quite acceptable sound for a head unit, no worse than through AUX. When Bluetooth is enabled on the smartphone, the connection occurs immediately after turning the key. If you turn on playback not immediately, already in the process of driving, you need to unplug and re-insert the AUX or USB plug . well, or restart the ignition. Has some cons: In the pauses between the audio tracks, there is a slight crackle, but not annoying. Since my VW radio has both AUX and USB connectors nearby, the device cable turned out to be long, hanging down and slightly annoying. But this is my subjective. The volume is 2-3 digits lower than through AUX. Perhaps that's all.
