2011 Sonata 6 CD changer
 

I am looking at a 2011 Sonata, but the seller says it has a single CD player. I have a lead on a couple of 6 CD players. Is there any reason why I couldn't transplant a 6 CD player into the place of the single CD player? One is identified as a Rockford Fossgate. Is that important? That one is cheaper.
