Seen on another forum...
| Quote: | | With Garmin you can have a POI file or dataset with a name such as redwood@55 - give it a proximity zone of 1 KM (or .5 miles) and your GPS will warn when you exceed 55 (Mph or Km/H) as you enter the proximity zone for that POI. |
Is that true? I've never seen it mentioned before.
I know you can have proximity warnings for POIs, and overspeed warnings (using the built-in speed data in the maps) but I've not heard of this combination of the two.

I'd imagine the current need might be for French/Swiss camera "Zones".

| The @55 on the end of the files title tells POILoader to set the overspeed to 55 mph/kph. The proximity distance can be set in the file or by using manual mode to tell it what proximity you want. |

Although it can be used as such, I find it a bit amusing that they class MS Excel as a 'text editor' without further info. Text editor it 'aint  |

any number in the file name will make POI Loader set an alert at that speed. It causes great amusement with Q8 petrol stations and 4-Star Petrol which give alerts of 8 and 4 mph respectively. you don't need the '@' sign in the file name.
the other way to set proximity alerts is to set them per POI in the file itself by adding @30, @40 etc in the file. this has the advantage of having a single file that offers multiple different speed warnings.
it DOES NOT give an alert ZONE though - it simply sets the speed and POI Loader uses it (too long in my opinion) default alert distance.

| Quote: | | POI Loader calculates proximity alert distance based on speed. You can enter proximity alert distance for individual Custom POIs in a .gpx file. You can also enter proximity alert distance for all Custom POIs in a data file using Manual mode. |
You can alter from the default distance. Camera Manager allows you to do so with the GPX file. IIRC you set the alert timing you want (i.e. 30 seconds) and it calculates the distance based on the speed limit of the data (i.e. x meters at y mph) and sets the Proximity distance accordingly. |

Ah well, you can't believe everything you read on other forums 
Here's something I prepared earlier :-
Speed and Proximity processing in Garmin POI Loader
Priority Order for Speed & Proximity Information
- Information from the POI itself (i.e. speed and distance for .gpx files - speed only for .csv files).
- Information entered in “Manual Mode”.
- Information derived from keywords in the File Name.
Alert Sounds
Two different Alert sounds are allocated automatically:-
Proximity Alerts are assigned “Passive Tone” = BONG, BONG {lower tone}
Speed Alerts are assigned “Aggressive Tone” = P-I-N-G, P-I-N-G {higher tone}
These can be overridden by the presence of an .mp3 file, whose file name matches the .csv or .gpx containing the POI’s. This comparison is not case-sensitive.
Individual POI settings
If the name of the POI is followed by an “@” sign and a number, that number is used to denote the speed portion of a Speed Alert. The associated default proximity distance is derived automatically from this speed.
Special File Names
If the file name contains numbers, a Speed Alert is created unless the file name also contains ‘Redlight’, in which case the numbers are ignored and a Proximity Alert created.
In addition to “Redlight” the following keywords also generate alerts:
“Gatso, Mobile, specs, safety, speed & Camera".
Unlike the case of “Redlight”, these become Speed Alerts, if there is also a number in the file name – otherwise, they are Proximity Alerts of 1/4mile (402m). (In other words, when specified alone (with no numbers), they generate identical Proximity alerts to “Redlight”.)
Whichever way they are set, Speed Alerts also have a proximity associated with them. By default, this is the greater of 1/4mile (402m) or the distance rquired to give 36 seconds warning.
Alert Implementations
The Speed and Proximity alerts detailed above, are all of the type “Along Road”. They are only triggered when you are at the specified distance (and travelling at the specified speed) on the road that contains them. When in Routing mode, the concept of the ‘road that contains them’, is extended to consider the whole route as one road.
Tour Guide Alerts
If the file name contains the (case-sensitive) phrase “TourGuide” (sic), then the Alerts are of the type “Tour Guide” (sic). “Tour Guide” alerts seem to be of a straightforward circular nature – where the proximity distance is the radius of the circle. They are always Proximity Alerts: any attempt to associate a Speed with them just alters the computed Proximity distance (a useful side-effect!).
“Tour Guide” alerts generated in this manner have the same audio associated with every POI (from an mp3 of the same name as the csv file).
gpx files
Using .gpx format, you have complete control of Speed/Proximity and Audio on a per POI basis. The POI alert type can be set on an individual POI-basis (through the presence or absence of the "TourGuide" phrase in the audio filename).
Missing information is defaulted in the manner already discussed.
The information in this FAQ has been derived from observation and experimentation. The version of POI Loader at the time of writing was V2.4.2 |

... and mine.
That's why I like the GPX alternative with the embedded 'Proximity' tag.[/b]
