I rode with a friend's bezza recently, I tried to connect my phone with the car's Bluetooth to play some music.

But the sound output is bad, especially the bass where it sounded distorted or for a lack of a better word "bunyi berterabur".

But it sounds fine if it's in radio mode or playing cd. The car owner said it's been like that ever since he bought it, ask service center also no proper answer. And all the phones that I tried (samsung, sony, iphone) from other people that rode along also sounded distorted.

Any ideas why? it's been bugging me each time I tumpang him now.

Tried YouTube also the same, usb and radio no issues.
