Problem wiht HU-850 stereo
 

Hei

I have a problem with my 2007 II gen Volvo V70 D5! Sometimes when I start my car the radio comes on but no sound will come from speakers, only some ticking noise. Sometimes it will start to play music after 10 seconds but sometimes it will not until i turn the engine and ignition off?

Has anyone had similar problem? Can somebody recommend what to check?

Best wishes

Check the ground terminal and radio wire terminal. Then switch the balance from right rear to right front and from left rear to left front on the radio control panel, I think this might be work.
