WARNING: You now need to remove the stereo by pulling it forward. Sounds easy but it ISNT! My only advice is, the stereo has 3 pressure clips at the top and 2 on each side of the dashboard/stereo trim.
If your lucky, hold your palms on the heater knobs and pull upwards jiggling with some force to try and free the side pressure clips!
If that fails, you will need to start prising from the top, but be warned, this can lead to surrounding dashboard being possibly damaged.
I didn’t take a photo (even though I wish i did) but one tip is to get a push bike brake/gear inner cable and thread it (like dental floss round your teeth) over the top left and top right corner of stereo/dash having prised a small gap with my trim tool, then wrapping the cable round your hand, pull towards you using it like a winch.

If you get lucky like I did and it comes free, you may have a few heater/electrics plugs to undo, then you have access to the screws holding the stereo to the dash panel you just removed!
If you fitting a new stereo, the you can buy the fascia from the main dealer for about £70 and it includes all new stickers for heater controls and such and comes with a DOUBLE DIN aperture meaning you can fit the DD stereos in it.
