I was trying to do a DC volt test on a single CD player. It also has a fiber optic connector. I tried to put a cd in during the DC volt test and it would not go in. Any help would greatly be appreciated. This from a 2011 XC90 SUV.

 

Why are you trying to check for voltage?

 

To see if it works. I'm probably doing the wrong thing. Any help would be great. Thanks for reply.

 

If your radio isn't working, take it to the dealer. You have a warranty for that reason
