How and if yes,can I copy music from car stereo to sansa clip+. I read reviews and one of them said they copied from stereo to clip but didn’t say how.

You’d have to check with the company that made your car stereo, but its relatively rare for stereo’s to be able to store audio internally.

Some car stereos (as well as some home units) have their own hard drives, to store music.

As long as you can save those music files as mp3’s on a PC, you should have no problems with that. The important thing is to contact the provider and see if there’s an option for you to transfer the audio files. Cross your fingers.
