If you are talking about a stocker... I have one. Will sell cheap.
I'm just saying this day in age you can buy a decent aftermarket stereo for about $150 that you can hook a thumb drive to. Thumb drives are getting pretty cheap, I bought a 16g one for like $13 and that holds a hell of a lot more music than 6 cds.

Meh if he can hook a aftermarket dc changer up to the stock nab head unit he can hook up the aux adapter it's pretty much plug and playExcept you're missing the point, he's putting in the factory nav system which only has one disc bay, which usually has the navigation disc in it. So radio only (bleh) unless he can wire the AUX in for an MP3 player etc.
That slave cd changer is pretty bad-ass though and would keep a fully factory look.
