I have a 98 Avalon. Recently the radio began "forgetting" everything.
It doesn't even remember that it was turned on. Works fine when the
ignition switch is on but every time the ignition switch gets turned
off, it loses all preset stations. Obviously the radio is not receiving
the permanent 12 volt standby power supply. I've looked at all of the
fuses in the interior panel and some of the lower amperage (5A) fuses
under the hood but haven't found any of them to be blown. Can someone
suggest where the problem may be?

Once you find the fuse, change it, even though it looks good - might
solve the problem without pulling the radio. ATO blade fuses
(especially some no-name imports from third world factories) have this
nasty trick where the element cracks and does not blow - and sometimes
the crack will be an intermittent open and work for a while... They
look just fine visually, but do a continuity test for voltage and they
are an open circuit.

Failing that, you might have to pull the radio and see if power is
getting to the connector.

If the proper power and ground are getting to the radio, it's always
possible the memory circuits inside the radio are hosed.
