I started to research this and the quickest place to find some info
about this was AOPA's GPS Safety Advisor. Sure the information is in
the AIM and I will get right back to it, but this was a faster link for
me:

Pertinant Quote:

"For en route flying, it's legal - but not wise -
to use an expired database, as long as the pilot has
available current information, such as current low
altitude en route charts, to manually check and
correct any data that's changed."

I will look later for more details about approaches.
