I didn't think anyone would use 92khz unless they were also using 67.

I was in a rental car (2002 Buick) a few months ago and it had an RDS
capable radio.  Since I wasn't driving, I messed around with it.  There
are about 3 or 4 stations between SFO and SJC which use RDS.  I hope it
catches on.  Supposedly everyone in Europe is using it.
