Q

I have a 2005 XC90 and I believe it is the display that is the problem. I have no sound and no digital display when I try to power it up. When I started to have the problem, the display and sound would come on when powered up, but would quickly go blank.

How do I tell which serial number will work for mine and how do I tell if mine has car-phone or not?

I am sorry if these questions are silly, but I do not have a lot of technical experience with these.

Thank you.

A: I can help you with that but I need to know what kind of sound package you have in there, please remove the black triangle from the door and look for the sticker, I need to know if it is blue or yellow let me know please, thank you,
