On this model taurus the faceplate is the control only. the radio is in the trunk. If your unit has the cd controls on the faceplate. all that has to be done is bolt a cd changer in the trunk and connect it in the loop with a wiring harness.
Several brands are available . Audiovox is the least expensive at about $160.00
Any stereo shop can sell and install a 10 cd changer back there for around $225.00
The reason most of them have the cd controls is production cost.
