How can I tell what's the speed limits of speed cameras from the POI of SC

 

I loaded POI of Speed cameras to my garmin.Then I tried to load different speed icons and alarm sounds accordance with those speed cameras. Now I have problem with these speed limits. There are so many different speed limits: 10, 15, ...70 mph. How do I know what's the speed limit on which speed camera? Will the correct speed limit icon show up if I load all of the speed icons and alarm sounds to my garmin? For example, the speed limit is 10mph, if I drive at 20mph, will the 10mph icon show up? And will the alarm sound "10mph" do the same? If I drive 80mph on a speed limit 70mph highway, will the 70mph icon come up?

Are you sure?

Are you sure that there are speed cameras in South Carolina? I don't see any in the file.

As for associating a single speed limit icon with the Speed Camera POI file: as you point out, there are multiple speed limits in the file, so you can't associate a single speed limit icon with the entire file without confusing things -- it would have to be generic, with no specific speed showing. What you do get is a banner that pops up at each location and shows you the speed limit for that specific location (if it has been put into the file -- some haven't).

Nuvi 660 -- and not upgrading it or maps until Garmin fixes long-standing bugs/problems, and get maps to where they are much more current, AND corrected on a more timely basis when advised of mistakes.
