I'd check the fuse first, there may be an in-line fuse, in addition to the one
in the fuse-box. If the fuse is good, then get a little test-light (if you
don't have a multimeter) and check the power wire (s/b red) for juice with the
ignition on (if radio power was switched on with ignition like in mine).
If you can't find the power wire, then it's a process of trial and
error. Others have said the antenna has a separate relay so I assume that
will work independently of the radio. If you have power, then try swapping
the radio out with the new one. I'd label the various speaker wires first, in
my 87 5KT, Audi used a color coding scheme like green solid/green-and-white
stripe go the same speaker. If you're not sure, connect 1 speaker at a time
until you've id'd them all. I used white tape to label them for future use.
