<<Does the company advertise the unit as VFR only?  Does it put in approaches?
  Does it do RAIM or Integrity checks?  Does it use WAAS for corrections? Does
the position solution update once a second? five times a second?>>

The company does not advertise one way or the other but the sytem is usable for both VFR and IFR depending on the equipment that is driving it and the aircraft in which it is installed.  The system is not certified but OP is pursuing certification of a similar system.

Approaches are included in the database, as are SIDs.  The Company is working on STARs.

RAIM integrity checks, update rate and WAAS capability are GPS functions.  GPSs are installed in the display itself and in the AHRS.  I don't know if they do RAIM checks or what their update rate is but they are not WAAS capable.  The system can also be driven by one or more external GPSs, in which case WAAS capability, update rate and RAIM checks will depend on the GPS being used.  OP offers its own remote GPS which is IFR TSO-able, WAAS enabled and very expensive.
