Default 1990 camry radio fuses question

Dear all: when I made a wrong connection with the battery, the radio
stopped working from then on. I checked the 7.5A radio fuse on the
dirver's side, it is not blown out. The Mannual shows there should be
another radio fuse in the engine fuse compartment, unfortunately there
wasn't. Is there really a second radio fuse??

Autozone has free repair guides. The one for your car's radio is:

I didn't see the radio in the wiring diagrams in a quick look, but you
can always measure the voltage at the radio power connector. If there
is the correct voltage at the connector, you can narrow it down to the
radio.

If you applied power to the wrong wire or reversed polarity you probably
cooked the radio (burned out transistor/diodes).

There may be a reverse protection diode that burnt out and is cheap to
replace. If the radio is worth it, you may want to try for a free estimate
from a repair shop before throwing it away.
