I've got a 2000 Maxima GLE. Over the last couple of years, my radio
settings would magically disappear on occasion. Both the CD and
cassette would simply be spit out when I went to start the car and my
stations would be gone. This is now happening regularly (daily). Any
idea what might be going on?

TIA,
David

How old is your battery? The voltage could be dropping too low on starting.

Even though all other electrical devices are working properly?

I believe he meant the temporary voltage drop while cranking the engine
to start it.  Often, if voltage drops below certain levels, the radio
memory will be erased.  This has happened to me with other vehicles.

In response to this post, I went and had a brand new battery installed
(I was still using the original 7yr old battery, after all). All was
well re the station presets until today when the old behavior surfaced
again.

Any thoughts what the issue might be at this point?

TIA,
David

Make sure that the battery and radio ground connections are ok.  The
service manual will show you where to find the ground connections for
the radio harness.  http://www.turbo6.net/vqtech/ESM/Nissan/Maxima/

Measure the voltage at the radio fuse when cranking the engine.

Reset the radio fuse, pulling it in and out.  Do the same to the radio
harness.

It could also be that one of the filter capacitors inside the radio is
defective and causing a voltage drop.

Good luck
