Tip & How-To about Garmin nuvi 250W GPS Receiver

Garmin POI, GPI, GPX, GDB and CSV and how not to be confused

GPX or CSV file can be converted to the proprietary Garmin format GPI format (Garmin Points of Interest) format using the Garmin POI loader v2.54 OR use the one bundled with the Garmin Map Source v6.15.11 at the time of posting if there is also a BMP file of the same filename then this will be added to the Waypoints Symbol.
If you put all your POI that you want to be added to the Garmin POI then place all them in the same folder prior to starting the POI Loader and they will be placed into sub-menus otherwise it will select the single file entries only.




However the Garmin Mapsource can't open this GPI format it is specifically for the SATNAV Device only open GDB, MPS, GPX and LOC files can be opened as standard. There are two ways that I know of that will convert this GPI back into CSV or the POI format if required you might like to open the POI content in the Map Source program.

First this can be done using GPI2GPS it does however cost 15 EUROs or its older brother GPSConvertor for an extra 20 EUROs will convert to all formats for all makes of device including Tom-Tom, Garmin and many others.

Secondly you can convert POI file in CSV format directly to GPX (exchange format) using the excellent GPXtoPOI Convertor v1.1.8 then import directly into the Map Source if you also want to use BMP that has been downloaded in Map Source you can replace the 8 default custom waypoint symbols located on your computer with your own or from the Tescos.ZIP file in this example that contains the CSV and BMP.



You can open these symbols with a graphic editor and use them as templates for creating your own symbols.You can add up to 64 custom waypoint symbols. These symbols must be in .bmp format and must be named numerically from "000.bmp" to "063.bmp." Custom waypoint symbols can be 16 x 16 pixels (small) or 24 x 24 pixels (large) and up to 32-bit color

Also check out my other POI tip HERE for help on how to create your own BMP's for use with your Garmin using Adobe Photoshop





It will also convert any GPX format into CSV format for use with the POI loader using the other button on the menu maybe this program would be best called GPXtoCSV instead to avoid confusion



.
And this one I saved for last If you want to transfer images from the Garmin use xImage and have your Garmi SATNAV connected.



For a full list of all POI sources then visit the Gamin POI Source another great website full of loads of useful tools is www.freegeographytools.com

If you are unable to use xImage it means that you unit is not compatible for example the Nuvi 250 will not be found and you may see this window

Can I download addresses from excel it computer to my garmin nuvi 205w?


Yes, but not directly. Most (if not all) of the Garmin Nuvi GPS units can not import files (import means the ability convert from one file type to another for direct use by the gps) such as those created by MSOffice, or other text, bin, etc. There are a few very specific file types that can be read directly, but the most common type is .GPX or "GPS eXchange Format" or .LOC which is sometimes called "location format" from EasyGPS/Geocaching.com. Most GPS brands and models can use these formats without trouble.

To use GPX or LOC, you will need a program that will take your spreadsheet files and convert them into one or the other. For more info on these file types and programs that can do this conversion, look here and here. I use ExpertGPS (the free version of this program, EasyGPS may work, too) and GSAK to manipulate GPX files and Garmin's POI Loader to send to my GPS from computer via USB cable. POI Loader is free, but ExpertGPS and GSAK are shareware (but are available to license fully for a very modest fee).

I hope this helps!

I have a book with points of interest listed with GPS coordinates in the form of: 12 557336 E 44o06413 N. How do I convert them to a format I can find on Google Maps?


you use a csv file or whatever form your brand of GPS accepts CSV= comma separated value. Type POI into browser and find poifriend finder site and look to see if there are already files available for your brand

Unable to send and open data sent to my Garmin GPS from Anquet map. I planned a route on my Anquet map software with wayponits etc but was uable to send it to my gps. I have enquired with Anquet and they said to save it as a GPX file which I have done and it seems to have sent it to my GPS. When I plug my garmin in the usb and open the file it shows the GPX file. When I go into waypoints on my gps there is no trace of my planned route How do you read this file on my GPS?


Currently, the POI Loader only supports CSV files because that is the format that most data vendors support. POI Loader may support additional formats in the future.

MapSource only supports .mps, .gdb and .gpx files. You can save files as .txt files if you wish to use this data in other applications.

Sadly Garmin does not produce any software which can convert .txt files.

However, this maybe possible with GPS Utility. Please note GPS Utility is not Garmin software and Garmin does not support this. Click on the following link for more information:

having problems with poi loader cant find csv file to be able to download files.unit is a garmin c31o


Here's how you get custom POI files on a Nuvi:

1. Download and install Garmin's POI Loader.

2. Create a folder on your computer, suggest Desktop, with a name like "Custom POIs". The name and location doesn't matter but you have to remember what it's called and where it is.

3. Go online and look for 3rd party POI files. Places like www.poi-factory.com have dozens if not hundreds of files.

4. Select ones you want on your gps to download. Make sure you are getting the files in the correct format. Newer Nuvis use *.csv files. Not sure if the C310 does. Download your POI files into the folder you created.

5. Plug your USB cable into the GPS and your computer. Wait until the driver finishes loading.

6. Run POI Loader and follow the instructions until you get to a screen asking for location of POI files. Point it towards the folder you created. Next tell it to load the POI files. After a few seconds it should give you a message "XXXX data points successfully loaded".

You should now be able to go to POI/Extras screen and see "Custom POI Files". Open that up and your custom POIs should be there.
