works on the 332c also
Here is one that isn't in your book. If you want an easier way to see your speed, push exit 3 times rapidly and a speedometer comes up. I don't know if this will work on other models or not.

Works on other Lowrance's also. I believe, if I remember correctly, you have to be on the 'map' page before pushing the exit button the 3 times.
Thanks for the Heads Up!
