I said in an earlier post I would write about what I thought was the sweet spot for using the c310x for Geocaching. I can’t believe how much faster and accurate it is than my older eTrex. Around my office I have several geocaches I can walk to in a matter of minutes. I now realize that you can optimize your settings and have a pretty good success rate.
You should know this screen well:
First, I recommend you put your mio into “pedestrian” mode.
Notice that when you select Pedestrian, everything that you’d need in a car is disabled. This is under the Route Options from the main settings menu.
Next, check out your advanced settings:
Pick Route Options. This threw me big time when I first tried to Geocache with this unit. Uncheck “Keep Position on Road.”
This will show your real position. Now, I have been Geocaching in downtown Atlanta, so this has worked well for me.
EDIT 090407: I remembered that the Advanced menu you see “out of the box” is NOT the same as I posted above. I had forgotten that I had installed “MoonBear’s” skin to get a faster fly-over. However, the “Keep Position on Road” option should be on the main advanced menu on a unhacked c310x. His skin is number 8 on the folllowing page:
Since I took these screenshots, I’ve skinned my Mio so my menus now look really different. Good luck!
