Do all gamma radio's have CD capability?

[SHOWMX at aol.com]

Hi Folks,

In my search for a used radio, I've come across a stumbling block here.  Some
of the gamma radio's out there have come from cars without CD changers in the
trunk or rear of vehicle.  Will these radio's still be able to control my
stock CD changer?

Thanks in advance,
