Hi,
I have a 2005 S60...(bought it last year)...equipped with an Hu-850 6disc CD player. Everything was going fine until one day, the lights on the unit shut off along with the radio controls on steering wheel. we reset this at my local service provider and the radio controls on the steering wheel are back on they work. However, the lights on the control of the unit itself remain off, but in working condition. The main display screen of the unit (the one that display radio stations...etc. ...) is working, but the rest are off. Can anyone tell me how to have this fixed? What is the reason why this happens? Any advice or help will be appreciated.

Thanks,
