I have the radio last week built into my VW Passat with series speakers, great sound, great features and easy to use. Making calls via Bluetooth is absolutely easy and the connection after getting into the car immediately because when the radio turns on. There are all adapter with this, connect, turn on, loshören. BT Audio works perfectly with my iPhone 3G, just can not control the radio from one, but in USB music it works great with Zappin and Quick Browse. Radio always starts with the setting last selected, just super, I'm thrilled. Lighting can be changed from blue to red. I would highly recommend it.
