Deleting maps from Galileo Luna

[tac306]

I recently got into diving and bought a majority of my gear used from a more experienced diver who had to get out of diving due to a diving injury.

I bought the Galileo Luna off of him and he had about 35 dives of his own on it. Is there a way to delete his dives off the device?

I've tried a master reset, but that doesn't seem to do anything.

Thanks much.

Nevermind, found the answer in a previous thread.
