In an earlier post I compared the C320, C330 and C340 GPS units.

At the time the prices were
C320 - $275
C330 - $320
C340 - $387

The current prices are
At the time the prices were
C320 - $275
C330 - $261
C340 - $329

It looks like have been significant price drops on the C330 and C340 but not the C320. I’m not sure why anyone would even consider the C320 at these price points.
