I was having a conversation about avionics with someone who wants to be able to shoot non-precision GPS approaches with a plane that currently has a KLX-135A. My opinion is, if doing any wiring, install something with WAAS, but he was thinking if a IFR GPS/Com can drop in (with the annunciator being the only wiring addition) that may be a good way to save money.

I am not familiar with Bendix-King GPSes from the 90s, are there any drop in replacements for that unit that can handle RNAV approaches?
 
You would also need an indicator (CDI). Not likely one was installed for a VFR-only GPS.

Just my oppinion but installing a non-waas GPS is a fools errand. The choices were limited and I'd be surprised if you could still get database updates for them.
