I rediscovered sound quality with incredible clarity, the treeble, the bass and the medium are so present that it feels like an auditorium. That's a long time since I had not driven a car radio as perfect. In one hour, I had control of all the functions of this unit. Bluetooth communicates very well with the new iPhone 6, all that was announced in the pub works great. For the price, this beautiful device is a wonder, yes, the 5 stars are well deserved. SONY thank you !!!
