I haven't even looked at it yet since I only just got the multifunction grip. I recall that the new firmware clears the last known location after 5 minutes now I think. Must try this out on my next trip ..... Wait that will be mostly in China. I shall have to look into this. On Wednesday, 2 July 2014, Peter Klein <pklein at threshinc.com> wrote: > Nah, John.
