 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?
 
 I've seen their units at shows and in the prototype EPIC, but am not familiar
with its capabilities.  These are questions I would ask.
