Hi, guys. I am now an Impala owner with an 08 LS of 54k miles. I do have 1 question. Accordingly to Chevy website, all 08 impalas are equipped with a CD/mp3 player standard but my car doesn't play mp3 disk I just burned. Is the player picky on the disk or I got it wrong such that mine is just a plain CD player without mp3 capability? The owner manual does mention something like CD player without mp3 though.
