AC90-100a Para 10.a.3
(3) The onboard navigation data must be current and appropriate for the
region of intended operation and must include the navigation aids,
waypoints, and relevant coded terminal airspace procedures for the
departure, arrival, and alternate airfields. RNAV STAR procedures may be
designed using multiple runway transitions. Operators not having this
functionality shall provide an acceptable alternative means (for example, a
tailored navigation data base). If no equivalent means are available to fly
the charted RNAV procedure containing multiple runway transitions, operators
will not file or accept clearance for these procedures.

Anybody have the link to the FAR that states what the requirements are for
IFR approved GPS's and the database currency for those units.
