Music on the USB in the car

I have burnt music to the disc but it doesn’t recognise it in the USB drive of the car

You need to check the specs of the car’s USB reader.  Did you reformat the disc by chance?

To what format? Many car stereos with USB input will only recognize and play .mp3 & .wma formats.
