The only thing I can think off is maybe he has some other piece of software programmed into it to pick up speed cameras or unless they're previous destinations he's been too before or saved addresses as that one in the photo is on a road... unless you drive to one of the locations to see whats there - anyway I'm puzzled now to be honest!:confused:

Ask him what he searched for last.

I'm pretty sure those are "city centers".

...on a road ?? surely they would be on a street ??

Seriously, what was the last thing he did a search for? Answer that and you will have answered your question.

Does it take a Super Hero to solve the mystery
 

The icon is for displaying PARKING :) It's one of the options in the "information on location/destination" area.

My blue bullseyes represent City Halls. St. Louis County has about 50 smaller cities and municipalities. I see these every 4 to 5 miles.

I actually drove right to one :genius: and it landed me at the front door of a City Hall for that city.

My blue bullseyes represent rest areas.

Cheers for clearing that up for us 'SuperGreg'

He said he has never searched for anything.

Even going to a search category will trigger that. I bet he or someone else did so without realizing it.
