E30 Zone

Hi I want to transplant this head unit into
My E30 from my E36. Thing is how does
The bugger come out? Is there a special removal
Tool you have to use and if so where can I get one?
Thanks Mike.

There's a specific tool for each make of head unit. Halfords do them for most brands.

Alternatively you can use two thin flat head screw drivers either side of the head unit and fiddle around until you find the release clips each side. Take the black plastic surround off first though.
