hey Gino what's up...I got mine from Right Scion too and they were great

...
anyway, i also have the 6 disc changer and encountered the same problem...it is the WMA thing...i think it only plays MP3 files...the first time i tried to make a compilation CD, the software i used didn't burn the WMA files on the disk

...so i tried it again, this time it recorded it, but like u said, it just skips the WMA files...
as far as the manual goes, i got one with mine...its not in the black book (the one with the first aid kit) that they gave you...i found mine separate and it was in the glove box in a plastic wrap...
enjoy the box man and congrats...also check out this thread for the AZ meet this coming Saturday and Sunday...
