Who mentioned anything about Cessnas?

Most of the pilots here have never flown airliners, or even any aircraft
equipped for the type of navigation under discussion. Note that the original
topic was VORs.

How many Cessnas have dual AP? What type and brand?

None, as far as I know. Even if someone is making it for Cessnas, it would
cost more than the airframe. (I'm talking about aircraft like 182s or 152s,
not jets.)
