Creating POI files


Need help with Magellan Maestro 4000 POI Editor

I just got this unit and can't figure out how to use the editor. The documentation is virtually non-existent. Is there a resource for more complete instructions??

Thank you everyone!

POI Coordinates

I've been experimenting with the red light camera csv file. Of course I'm confused... Why do the coordinates for all the entries not represent the actual ( or very close ) location that the camera shows up on the Nuvi map?

my custom poi file has "Alert Imformation"

how do i get rid of this? it show distance and speed then the address of the location?? anyone else have this problem?

i created the file in excel csv extension.

when i am done i will have all the 7-11 locations in Ct i can post.


When you load an icon and poi's where do they go" I loaded some on my nuvi 350 and it said down load successful but I don't know where to look to see if they are there....I thought the icon would go to the" where to" screen but it is not there....I need some enlightenment.....

transferring files on the Garmin 350

When I try to transfer files to my 350 using the POI Loader I get an error messgae saying
"There was a problem copying the data to the data card'
The System cannot find the path specified" Anyone know the answer to this?

Change in some POI format???

Maybe what I am asking has already been thought about... if so, chock this up to me having overlooked it on the site.

I see many files that have the following type of lines in them:

long, lat, name, name

Creating custom POI daily list?

I drive for a living to service clients security systems. I do about 10 houses/business a day. I am wondering if there is a way I can type all the addresses to a SD card at the beginning of the day, then simply plug the card into my gps and avoid having to type then in on the gps screen (i have thumb fingers)

Nuvi 350 Only displaying 50 POI's

I too am quite new to the POI factory.
I jsut installed the Ontario Provincial Parks and the Quebec Parks POI's on my Nuvi 350.
Only 50 of each show now in the Nuvi
Any ideas where the other couple hundred are hiding?

POI tools

Being new to the forum and the topic of POI creation, I'm looking for some advice as to the availability of software on the Internet that I can use for this purpose. If there are any worthwhile sites I can check out, I'd appreciate suggestions.

Field Lattitude and Longitude

This site is great! Thanks.

I am trying to find the lat and long of a place in the middle of a field that has no "known address".
How is this done?


What are the fields in a POI File and how many fields can one have?

What are the field designation in a POI file and how many fields can a record have?

For example (only an example).... Looks the following record:
-124.1904,40.7749,"Flying J - Eureka, CA","3505 Broadway St, Eureka, CA 95503,
(707) 443-1891"

1. Why is everything in quotes? I notice some files are and some aren't. If it works without the quotes, why put them in?

Garmin c330 not accepting POIs

I have a Garmin c330 and tried to load some POIs onto it but got a message saying there was not enough space.

I bought a 1GB SD card and put that into the Garmin. When I try to load the POIs onto the machine it still says that there is not enough space.

How can that be? What am I doing wrong?

Any help would be incredibly appreciated as I'm pulling out my hair over this one.

Is there a way to test an mp3 file without a route?

I created some mp3 files and loaded them into my Nuvi 350.
Is there a way to test them using the Nuvi 350 so I can tell how they sound there - without having to go there in a trip?


How do I know? (standard / custom POI)

How do I know I am not duplicating POI's that my Garmin 350 already has loaded?

And what would be a reason for duplicating them? Wouldn't the duplication just be "less efficient" use of storage?


POI Loader looses files ignored in manual mode

My c340 looses the .cvs files during POI Loader "manual" mode if I choose the ignore this file button. What am I doing wrong?

Difference in Coordinates (Google vs Terraserver)

I put the address in (6570 CR283 Kaufman, TX)on Google Earth and get these coordinates, 32.62021, 96.33689 and on Terraserver, the same address gives me 32.63391, 96.35117. Why would there be a difference? I am going there tomorrow, so which one would I use?

Running POI on SD w/ Nuvi 350

Ok, I'm a newbie. Got my Nuvi 350 and want to put some POI on it.

I see the POI comes in two files: 1.A csv file and 2. a mp3 file for sound.

I set up two folders on my pc and downloaded the files I think I want.
I would like to load them on the SD card and run them from the SD card on the Nuvi 350.

1. Is this possible?

Why can't I see all info

I am trying to get into making POIs. For an example the POIs for Cracker Barrel US stores when I open it in Excell I can see the Lat., Long.,Name and location but that's all. On my Garmin Nuvi 670 I see the town, the phone number and some other items. I want to make a POI of locations in Ontario, Canada showing the Name, Address, Phone Number, Etc.

Understanding and creating GPX files

I have seen how to create a csv file in Excel, it is simple enough. GPX file creation however seems too complex for me to grasp an understanding of, mostly how to create this kind of file. Is there a GPX creator for Dummies out there?

Time Zones

My wife and I do a lot of travelling around the USA and love our Nuvi 350... One deficiency in the unit seems to be it's inability to change time of arrival info, etc. when crossing into another time zone....
