Default distance for speed camera?

 

I was using Garmin POI Loader to install POI file to my GPS unit.

When installing the speed camera file, the POI Loader offers two alert options:

A) Alert when speed is greater than the Alert Speed (default is 0)

B) Alert whenever you get close to a point (default is 1969 ft)

My question is:
If I chose option A, how early I'll get the alert?

Also, I'm surprised that there such an option that the alert was triggered when the driving speed is greater than posted speed. Thanks!

To get to the options

To get to the options mentioned, you were in the Dialog brought up by specifying the you wanted "Manual" (rather than "Express") mode

Understanding Speed and Proximity Alert Information

POI Loader automatically scans .csv and .gpx data files for speed and proximity alert information.

You can also use Manual mode to specify default speed and proximity alert information as needed.

Speed Information

Speed information can be included in the file name or in the names of individual POIs within the file.

POI Loader determines speed information based on the following information, listed from highest to lowest priority:

Speed information included in the name of the individual Custom POI. For example, a POI named "SpeedZone@30" will have an alert speed of 30 regardless of the speed information specified in Manual mode or in the file name.

Speed information entered in Manual mode.

Speed information included in the file name. POI Loader interprets any numbers in the file name as speed information.

Proximity Alert Information

Proximity alert information can be calculated automatically based on speed information. It can also be included in .gpx data files or added in Manual mode.

POI Loader determines proximity alert information based on the following criteria, listed from highest to lowest priority:

Proximity alert information listed for individual POIs in a .gpx file. This information overrides all other proximity alert information.

Proximity alert information entered in Manual mode.

Proximity alert distance calculated by POI Loader based on speed information in the file name or in individual POI names. This calculation uses the following formula:

Prompt Distance = 36 seconds * Speed.

A default proximity alert distance of 400 meters/0.25 miles if the file name contains the word "redlight."

If there is a TourGuide audio file attached and no other proximity alert information is available, POI Loader assigns a proximity alert distance of 0.25 miles.

See Creating Custom POI Files for more information.

NOTE:
The "speed" in the phrase "Prompt Distance = 36 seconds * Speed." refers to the speed from the POI file - NOT the speed at which the device is traveling.
