I have recently purchased an Audi A3 1.8T and with it I got a blaupunkt radio with cd changer. I assume it came as standard. Having finally started saving the money for a replacement it occurred to me that I don't have the tools to remove this head unit.
Does anyone have these tools or even have a picture of them so I can see what could replicate them?

Also anyone know any good websites to get cheap head units from?
