My car has factory Bose sound system. When i first connected device it didn't work. There were no sound output due too missing amp on wire (remote amp cont.) on the harness. I had to cut some wires and modify the harness. After connecting the amp on wire to the ACC wire, 4 Door speakers started working. But sub woofer is not working. So i am not satisfied with audio. I wrote to the tech support and they said that you cannot use original car's subwoofer. There is no Info about this in the product description.
In short: I'd recommend it. I bought the top version 6x128Gb for my J10 and it fullfilled me completely. Wake up time - less than 1sec, big screen, good enough sound. Easy installation, the detailed manual is available online. Teyes online along with Voice commands gives you great additional features. Steering wheel buttons work perfectly. Indeed, this is a decent choice.
