If the reset described by justaskjoe doesn't help, then check the power cord. There's a fuse inside the power plug, held in by a screw ring which is notorious for coming loose. Make sure the fuse and spring are in place and the ring is screwed on firmly. My daughter's C340 stopped working because that ring came loose and the fuse fell out. Also remove the unit from its mounting cradle and snap it back in to ensure good contact.
You may solve your problem by resetting your gps. using a fingernail, carefully pry the thin frame off from around the screen. under the frame is the reset button. just push it once to reset.
