This my first post on the forum and I believe my info is important. Like many of you other poor souls that had their radio in their Volvo fail mine did too. So after doing all the basic troubleshooting steps, I took my wife's 2006 XC 90 to the dealer to have the system checked. I was told that it failed internally and they could replace it for $1700 parts & labor. After picking myself of the floor, I said no thanks. So I went to Ebay and found a replacement for a $130 @ LKQ online. I installed the replacement and nothing, not compatible by part#. So I contacted LKQ and they are sending a replacement, great customer service by the way! So now the reason for my post, not wanting a big hole in the dash I reinstalled my old defective unit and Lo & behold it WORKS!!! I don't know what caused it to work but it does, so others might do the same? Maybe some other DIY's may try and remove and reinstall their unit before getting a replacement. Hopefully this helps save someone else some $$.

 

It works for now, but I bet it won't last.

 

Maybe, I didn't cancel the other one I ordered. I know it may fail again but it may take days or months, who knows? I think with Volvo's record it's a crap shoot anyhow. Anyway my fingers are crossed.

 

sounds like the iam is intemittently failing. radios from other cars will not work because they need to be programmed to the vehicle.
