Radius Alerts - Nuvi 50LM

See http://www.poi-factory.com/node/13958 .Good information for what you are looking for.

Now I know how to set up directional alerts.

Does not work on a NUVI40

There is an error in H Hannah's writeup. It's minor but can lead to some confusion. He states

Setting a proximity alert - or distance - is just that. It sets an alert which will trigger at the specified distance regardless of speed. The distance for a speed alert varies according to the speed of the vehicle. If you have for example a speed camera and the speed is set for 35 MPH, the alert sound will trigger approximately 36 seconds before you reach the location based on the speed you are currently traveling. At 35 MPH you are traveling approximately 51 feet per second. That means the alert will trigger around 1850 feet before you reach those coordinates. But if you are traveling at 25 MPH and approach the same point, the alert will not trigger until you are 1320 feet or a 1/4 mile before reaching that point. So distance varies only when a speed is set for a location.

TourGuide should work on your unit.You will need wav and soxe.exe . See http://www.poi-factory.com/node/25730 .Just be sure to name your files the same except for the extensions.

TourGuide Cracker Barrel.csv
TourGuide Cracker Barrel.wav

It should.

What specifically failed?

...seemed to make no difference in the alerts. What difference is is supposed to do?

I don't believe my NUVI40 has the tourguide feature.

I have the Garmin 765t. I dont know what to tell you, other than I know that my TourGuide POIs all work on a radius. I use for example, a file formatted like this works: Covered Bridges_TourGuide.csv

You use the word "TourGuide" in the csv or gpx file name and then load it using poi loader in manual mode.

As per the link that was previously posted.

Your nuvi does have the TourGuide feature.

So let's make sure of some other points.

One possibility might be double extensions on the bmp and wav files. Have you done this exercise?

Also TourGuide is spelled with a Capital "T" and a Capital "G". That often throws people the first time.

Actually do not know if this makes a difference, but on my nuvi I have a setting under "Tools > Settings > [down arrow] > Proximity Points >TourGuide that can be set to "Off". I set mine on "Prompt".

Let us know your settings, etc., please.

I think my alerts always work on a radius, whether or not I use the TourGuide keyword or not. Am I missing something?

I use the manual method on POILoader and pick a certain distance.

The "Manual" mode of POI Loader is indeed where you must set proximity for POI files of the .csv variety. Using .gpx files you can set proximity internally and use 'Express" mode or use "Manual" mode if the .gpx file has no internal distances.

I am not sure why you say that all your working alerts are on a "radius" basis unless you are setting distances of 30 meters or less (98.4 feet).

If you look around the forums, you will lots of discussion about the fact that people who are making their own POI files and not having them work have set the "POI" more than 100 feet from the center of the road on which they are traveling.

I would suggest you create a file of POIs around your own location and then learn to do Simulations so you can sit at your computer - create something - safely disconnect - run a simulation - learn something - try again until you are comfortable.

By just using poiloader to load a file in the manual mode and set a distance you just get what we call along the road alert.If you put TourGuide in the file name just like I typed it.You will get a radius alert of 1/4 mile.Using poiloader in manual mode you can increase the radius setting.You will need the sound file to go with it as I stated on above post with wav and sox.exe.

Nope.

Did that already. No difference.

For instance, the RLC POI file from this site.

Redlight-Cameras.csv
Redlight-Cameras.wav
Redlight-Cameras.bmp

I load them manually with 2000 ft alert and use sox.

At all camera locations for my home city there is only one camera (pointing in only one direction).

No matter which direction I simulate driving, the alert sounds. To me this means it is a radius alert. Am I mistaken?

It doesn't mean that because the RLC POI's are on intersections. So they will alert from any street and any direction that crosses the intersection. Try it on something like a restaurant POI, then simulate a route on a street that is parallel to the street the restaurant is on but within the radius you set. You wlll find it alerts with TourGuide but not with plain proximity without TourGuide.

Thanks. It works. I didn't use the resturaunts, but I could use deer crossings. I have a few instances where, at T-Intersections, if you turn one certain way it is a deer crossing.

With TourGuide, I got an alert every time I got close to the coordinates. Without TourGuide, I would only get the alert if it is on my route.

I'm putting you in for a COW.

Since your 2000' alert is nearly a half-mile, a radius alert would give you a false alert you when traveling on nearby streets parallel to the redlight camera, something that I doubt is happening and certainly not something you want for a redlight alert. An along-the-route alert, which we believe is happening for you, will only sound a 2000' alert if along your route.

Note that setting a 2000' alert manually for redlight or speed cameras is probably counterproductive since the two files from here at The Factory come with preset alerts for these two files.

Try this:

Create or find a POI file the has maybe one location, say your City Hall and call it cityhall.csv, then load it to your nuvi with alerts set for 2000' (making sure that your csv location is right at the street in front of city hall and not set back too far from the street).

Now create a route that takes you past city hall and drive or simulate the route. We are suggesting that 2000' feet before you pass City Hall, you will get an alert. Now create a route that takes a street one block away parallel to City Hall. We are saying that you will not get an alert even though you're within 2000' of City Hall.

Now delete the old POI file and reload the same cityhall.csv file, BUT having renamed it cityhall_TourGuide.csv. Do the two above drives or simulations. We are suggesting that as a TourGuide, both routes will give you an alert, both passing right by City Hall and driving the street parallel to it but not actually passing City Hall. In fact, with a TourGuide, even when not on a WhereTo route, any time you're within 2000' of City Hall, you'll get an alert.

One final suggestion above and beyond what's already been suggested to you. I think someone discovered recently that TourGuides require a linked audio file (mp3 or wav) to work. A TourGuide file may not give a radius alert when it's been loaded without an associated wav or mp3 audio file. Don't ask me to find the thread that suggested this, but it was here at The POI Factory and was written in the last few months.

[Edit] Darn, and as I typed this, it appears you figured things out and posted your success two minutes before my post.

All's well that ends well.

Then why does it default to just under 2000 feet when you add the keyword Safety?

Really? I don't see it in POIEdit.

Someone said that all Garmins now use wav files. MP3 does not work anymore.

Yes indeed. Thanks again.

For me, with no added changes or effort on my part, the stock Redlight-Cameras.csv from The Factory is set to alert at 1320' and the Speed-Cameras.csv is set to alert at 0mph or higher (which I think also occurs 1320' in advance at the POI location). I've tested these files at redlight camera locations and speed camera locations and these defaults built into the files straight from the Factory here work as I want them to: I get both redlight and speed alerts. I don't rename the files or otherwise alter or set additional alerts to these two files. I can't answer to what POIEdit sees since I haven't found the need to use it. Similarly, I haven't found any use yet for csv or gpx files containing the word Safety so can't respond to that question either.

Regarding wav vs. mp3, let me clarify by expanding my response. I believe TourGuides need an associated audio file to work properly; either a mp3 (or wav installed with sox) audio file for those nuvis that can use mp3 audio (yes, there are still many of these nuvis in use even though Garmin's new models aren't among them) or a wav audio file (installed with sox).
