You need a T10 (Torx Size 10) Screw driver to do this.
Remove the Volume knob from the main unit and there is a small T10 screw.
Turn this COUNTER clockwise 90 degrees or so and pull out. This will swing
the main unit outward towards the passenger seat.
Once that is removed there are 2 Pointed Gold "things" on the bottom of the
Business CD. Next to each of these is another T10 screw. Turn these both
counter clockwise as far as you can. This will allow for the business CD to
be pulled out and have access to the rear of the unit.
Reinstall in reverse order.
How do I remove the front dash/CD player cover so that I can access the rear
of the unit? I need to add a device to the FM antenna. TIA
