How do I remove my Audi's factory stereo?

I have a 92 Audi 100 Quattro CS with a Bose sound system.



I want to know how to take out the factory stereo because I do not have those one things to pull it out. My back speakers are not working and my passenger speaker is not working. Which leaves me with just one speaker the driver side.



I think its the head unit so I want to replace it.How do I remove my Audi's factory stereo?The only successful way to remove the stereo is to get the correct removal pins, their not expensive, Halfords sell them or try ebay. If you try to do it without the correct pins you are likely to jam the stereo in the dash forever.
