Hello! I have a 2004 300M Special, and it came with a factory AM/FM cassette player and 6CD Changer. I was just wondering if i can replace that cassette player with a OEM Chrysler CD player and keep the 6 CD changer (since every 300M that came with a CD player has a 4CD changer). I think that everything should be fine if replace it...but still it's better to ask. Thank you
