ive done it.
first take out ur stereo and the metal surround.
on the plastic bit where your stereo sat inside, on the side of it there are two torx screws, undo them.
now that u got the panel underneath the heater controls off, push in the heater controls a bit slightly.
now be very careful and gently play around with it until it comes out. i was rough with it and scratched some of my dash off
when u got the heater control panel out, undo the three clips on the top and two clips on the bottom and it will open up.
hope this hopes
any questions, pm me
