Just bought a 04 xc90, second one I've had w/radio lights up, no volume, are they known for bad radios? Don't guess there's a mute thing needs to be unmuted? Other one CD played, but no radio, this one no CD either, won't let one go in, may be full and stuck. Any easy way to find out?

 

There's three main components to the sound system - the head unit, the power amp and the antenna amp. If you get no sound on any feature (AM/FM/CD) then its likely to be a problem in the head unit or power amp. if you can get a CD to play (test using a store bought CD not a home PC burned one) and have sound then it may be the antenna or the head unit. What happens when you turn the volume all the way up - do you hear any sound (ie crackling, white noise etc)? You can check eBay for like for like replacements - but I'd pull the head unit and test on a bench first (ie wire some speakers directly to the head unit etc to test the output sound etc)

 

The only thing I get is the screen to turn volume up, nothing changes when you turn ****... press menu and the radio options come up, but nothing makes any changes, CD acts like it's full, won't do anything. What's a good replacement that is not too expensive, all I want is radio and CD player.
