I've got an Astra MK5 with the original CD30 head unit. I'm trying to remove it so I can fit my new JVC double-din, but I can't seem to get the bloody thing out. I've got allen keys in the four holes and it feels like the clips have opened, but I can't seem to get it out.
I tried to give it a push from behind, but I can't see to get my hands behind it for love nor money.
What is the best way to remove it?
