Car radio MP3 player advice needed.
 

I have just bought a "Shintaro USB MP3"
player, which plugs in to the car's
cigarette-lighter socket.

I got it working by downloading some of my
MP3 files on to a flash drive, which I
plugged in to the unit.

The quality of the sound is faint and
terrible, and I wonder if anyone has had
experience with this unit, and if there is a
work-around.

If not, is there a high-quality alternative
available?
