How do you remove the radio from a Jetta?

This is a partial answer. It appears there are two methods, depending on the vintage of the Jetta. These methods require special tools, which are available on the web for less than $20. One method requires a "DIN" tool set, which is a pair of U-shaped rods. These tools match up with four holes at the left and the right side of the radio. The other method requires flat keys which are inserted above or below the radio. The following site has pictures of this method. http://www.autotoys.com/x/cust/product.php?productid=246 It also may be possible to make the keys out of an old credit card. A related issue is that the radio must be reset if power is removed, such as when the radio is disconnected or the battery runs down. This is an anti-theft feature and requires entering the reset code for the specific radio. This should be a separate topic on Wiki Answers.
