I have experienced that most of the CD changers in the volvo cars or any other car that came into the market before year 2000 were not having the MP3 option. you can check that out by simply inserting an MP3 CD
. Anywyas if you are intersted to get an MP3 option u can get another Deck or CD changer installed in your car. There are a lot of cool accessories for ur car available in the market.
Will come to u later Ba bye
