Not necessarily true. You are referring to "old" technology here (TSO-C129A GPS) in what is a fast changing environment! With a suitably installed TSO-C145A or TSO-C146A GPS/WAAS receiver, my understanding is that other equipment appropriate to the route to be flown isn't required, neither is an alternate with a non-GPS approach.
