Does anyone know the details of the LX and EX stereos in the 2009 Civic? Will the LX and EX units play a CD-RW ... or just a CD-R? Does anyone have experience with the USB port on the EX stereo? All I can find is that you can connect your mp3 player to the car stereo via this USB port. Will a flash drive with MP3s on it work as well? Or must the unit connected via the USB be a mp3 PLAYER? Any brand? All brands? Anyone with knowedge or experience here will be most appreciated. Thanks, Gary
