[BC] RDS numbers?

[Gary Peterson]

I have been searching for some statistics on RDS without any success.

I'm wondering what percentage of FM radios (including car, portable, tuner,
etc.) have RDS display capability.  They seem to be a somewhat rare
commodity in spite of quite a few stations capable of displaying song
title/artist.

Any info would be appreciated.  Just curious.
