Shadow and JC, I'm trying to attach a link. If it doesn't work, go to macintoshlabs.com and look for the car stereo downloads section. They still list the CD changer there, but looks like they have upgraded the head unit to much fancier.
Sorry, can't copy the links.
It really doesn't matter since the stock McIntosh head in the GT doesn't have the required connections to use a cd changer directly. If you change to the MX406 head then yes, but it really gets sticky here. I appears the MX406 head was only sold in Japan and you need an FM adapter to broaden the band width so that you get all the channels. Also, the cd changer is harder than that to secure. I'm still thinking though. I'm going to call McIntosh sometime this week and ask some questions about our unit and the MX406.
