Where in the CASA regs will you find the minimum requirements for the number of course displays (CDI's) in a stand alone GPS installation (single unit) in a two-crew certified aircraft?
Logic says both the Captain and F/O should have a display in front of them - but where is a specific reference?

TWO PILOT OPERATIONS
52. For aircraft operations that require two pilots, the
display of GPS derived navigation information is to be
duplicated to the extent necessary to enable either pilot,
when in control of the aircraft, to view the azimuth
navigational information within their primary viewing
area. Receiver/control panel placement is to be central and
accessible to either pilot to enable the non-flying pilot to
effectively operate the equipment and utilise the receiver
display, where necessary, to perform the cross checking
function. The GPS annunciator panel, which displays
MSG, WPT, HOLD and APP lights, must be located such
as to be either clearly visible to both pilots or duplicated on
the respective instrument panels.
Note: In some installations it may not be feasible to provide
duplicate displays of GPS derived information.
Operators utilising installations where the navigation
displays between the flying pilot and non-flying pilot
differ should provide adequate description of the method
of operation in the AFM Supp, Operations Manual and in
the flight crew checklist (as appropriate).
SINGLE/DUAL PILOT OPERATIONS WITH INTEGRATED ELECTRONIC DISPLAYS
53. Where an aircraft is fitted with electronic
multifunction displays that form part of a Flight
Management System (FMS) and the GPS is integrated into
that FMS, the GPS control panel is to be placed in a
position that ensures all controls that are normally
adjusted in flight are readily accessible

Possibly a starting point for you.
