how do you take out stock 1993 audi 100s clarion head unit? thank you

 

I'm the car sterio manager at Circuit City and you have to use theU shape removal tools sold to remove Ford factory radios. With all the radios I have done at Circuit it's the only tool I use for the later model Audi's to get the radio's out. They cost about ten dollars at Wal-Mart. I hope that helps
