Use the same two mounting brackets for the radio and heater/air conditioning control assembly.

Shift the driver's seat backwards, then loosen four bolts that hold the changer unit in place. Lift up the changer unit until the electrical connection disconnects, and if you're replacing the unit, remove the four mounting screws on each bracket so you can easily take it off and put everything back in reverse order.
