Proximity Alert distance

In EPE select your file then chose "EDIT" then "Replace field name" then "Field name" scroll and select "Proximity" then enter new distance value. Exit by "Replace all"

Same routine for speed. Field name select "Speed" and enter a speed value.

This info is straight from POILoader help.

To load POIs using Manual mode:

Turn on your Garmin GPS device and connect it to your computer. If you are using a card reader, connect it to your computer.

Open POI Loader and click Next.

Make sure the appropriate device appears in the Device field. If not, click Find Device. If you have multiple devices connected to your computer, select the device you want from the drop-down list.

Click Next.

Select "Install new custom POI's onto your device."

Select the directory where the data files can be found. POI Loader detects all .csv and .gpx data files within that directory. If you have data files saved in additional directories listed under the main directory, POI Loader creates subcategories for those Custom POI files when they are loaded onto your unit. For example, if the main directory contains additional directories called "Food", "Resorts", and "Stores", POI Loader creates subcategories called Food, Resorts, and Stores on your unit.

Select the appropriate units for distance and speed (Feet and MPH or Meters and KPH).

NOTE: POI Loader uses these units to interpret the data within the data files. If you select units that are different from the units used in the data files, your speed alerts will not be accurate.

Select Manual and then click Next.

Adjust the settings for each individual data file:

If you want to ignore certain files, check "Ignore this file?".

If the file contains proximity alert points, check the appropriate box.

Select alert settings:

To set a speed alert, click Alert when speed is greater than the Alert Speed and enter the speed at which you want to receive an alert.

To set a proximity alert, click Alert when you get close to a point and enter the distance you want.

Click Next.

Repeat Steps 8–9 for each data file you want to load. After you choose the alert settings for all data files, POI Loader installs the POIs on your device.

NOTE: This replaces any existing Custom POIs installed on your device.

Click Finish.

It sounds to me like you are confusing proximity (distance) alerts and speed camera alerts. Proximity alerts can be applied to any POI file (such as the Rest Areas file) and you specify the distance that you want to be alerted. Speed alerts used on speed camera files alert as you approach the camera location when you exceed the posted speed.

I have the speed and redlight camera files in one folder on my computer. I have a question on proximity alerts for the speed and redlight camera files when using PoiLoader. Any idea on what PoiLoader uses when you choose Express (Recommended) over Manual inputs for proximity distance? What settings do you guys use? I usually use 250m for redlight and 500m for speed cameras.

I you enter "0" for Alert when speed is greater than the Alert Speed, if you are going under the speed limit, is there any alert even given on a speed camera?
