If you don't have bluetooth streaming but have Media Station that have USB input you can make your Z10 play MP3 on your car.
1. Go to setting
2. Storage and Access
3. Go all the way down to usb mass storage and turn it on.
4. Then plug it in to your car.
5. Wait a few min for the system to read your Z10 and there you go. It works :)
P.S. it will charge your phone at the same time.
