Hi. Bought a pro_ceed a couple of weeks ago and yesterday I noticed the car stereo sound has lost its clarity when listening to USB mp3's and fm radio. The sound is like listening on mw! Changed all the tone settings to default and started from scratch and still poor sound quality. Put a normal cd album on and the sound was perfect so don't understand why this is happening on USB and fm. USB is Sandisk so it's not a bad manufacturer.
