There is as much confusion over the database being up to date as there
is over who can do major work on an experimental airplane.   Major work
being defined in your operating limitations.

When an IFR GPS is installed the "installer" == you, must insert an
addendum into the airplanes operating manual.  IN the addendum, it will
say how the currency of the data is verified.

My Bonanza had it specified as "I the operator  had to verify all the
data for your route and approaches be current in the database."  This
allowed me to keep track of the changes on paper if any and update the
database when the number of changes got to large to track or an approach
I used a lot was redesigned. 

Not all avionics shop word the addendum this way and short cut it by
requiring a current database.

You write the addendum so write it to give you some flexibility. Of
course with this flexibility comes the responsibility to know whats
current.  If you don't want to track that, subscribe for automatic
updates. 

I used the the "Air Chart System" to track changes, which at the time
was much much cheaper than a Jep subscription.
