How to fix a non-working radio in my Audi 80?

I recently purchased a used Audi 80 and found that the radio is not turning on. The display is blank and none of the buttons seem to work. What could be the issue and how can I fix it?

The first thing to check would be the fuse for the radio. It may have blown and needs to be replaced. Check your owner's manual for the location of the fuse and how to replace it.

If the fuse is not the issue, it is possible that the radio itself is faulty and needs to be replaced. Try to find a used radio from the same model and year to save on costs.
