Hi guys, i have problems with the sync. It doesn't want to work, like it turns on and off, but it doesn't make sounds. Tapping sound works, but i can't turn the radio on and listen to music, like when i'm tapping on the radio icon nothing happens, and the same thing is with Bluetooth and AUX, i can connect my iphone with bluetooth, but when i turn on music, it shows tha name of the music but no sound.
