Thanks for this service - I will definitely be sending you a donation! Just got back from a moto ride from Canada to Costa Rica. Before I left with my friends we decided each to get different set of maps so that in that we could compare. One of us got the Garmin maps, one of us got a set made by a Mexican provider, and one of us took advantage of your service. We all ended up using your maps, as they were by far the best!
Now, I am heading to ride in Europe in the next couple of weeks, so I downloaded from Italy to Eastern Europe. I took note of the issue with downloading different maps sets and took your advice to load JaVaWa GMTK - and gave the first down load a different name. Still when I loaded the second set it overwrote the first - and then when loaded into Map Source crashed the program everytime I tried to load the maps. I removed it with GMTK and reloaded the original …and it seems to be working again. But now I am confused as to what you mean by changing the ID - which I thought I had done…but whatever change I made - seems to result in Map Source crashing…
What category should I modify - Family ID, Name on Computer, Name on Device, Folder name…?
THanks
If you already have one OSM Generic routable mapset installed, you need to run Javawa GMTK first and modify the Family ID, Name on Computer and Folder Name first before installing a second mapset. Keep Mapsource (or Basecamp) closed when you do this and it should work. When you run the installer of the 2nd mapset, the installer notice that the mapset is already installed, click OK to proceed.
After the 2nd installation, run Javawa GMTK again to check if the second mapset is installed without problems and to modify the latest mapset name and ID so that you can install more OSM mapsets in the future.
Hi All,
First of all thanks for the great service of garmin.openstreetmap.nl
I am not sure if it was mentioned before, but I want to attend everybody on the programme: GMap tool (www.gmaptool.eu/en), which allows you to change “map set Names” on the .img files directly.
By this method you can just 1) download the .zip file (containing gmapsupp.img) from garmin.openstreetmap.nl. 2) Copy the unzipped gmapsupp.img to your device and 3) change the map set name with Gmap tool to the desired name to be shown on your device. So no need for Basecamp.
Hello everyone,
My first post, please be gentle 
I need maps for a motorcycle GPS Zumo 660LM. It is for a friend of mine but he needs maps of Russia and India. GPS itself was ordered with maps of Europe. Am I safe to assume that if I download the ZIP (img) maps of India and Russia on a SD card, he would be successful in navigating though both those countries on his Zumo? The GPS is on order and I am getting prepared so any help would be greatly appreciated. TIA
Splitter question:
I have an old (but waterproof) Garmin GPS V that has served me well on my motorbike. I want to upgrade it with a OSM map, as I have had great value of Lambertus’ service on my Garmin nüvi 30.
The GPS V has *very *limited capacity, so I guess that I will have to use the Splitter program - but is this possible with Lambertus’ maps? As I understand, the tiles on http://garmin.openstreetmap.nl are the result of Splitter’s work - so if I want even smaller tiles, I have to start over by myself? Is this correct?
In any case, advise on how to produce the exact same maps as Lambertus’ - just with smaller tiles - is appreciated.
BR,
Jakob
Hi Hack,
For ease of use I suggest you build a custom map on the site, using the manual tile selection option and also make sure you choose the 2nd option “testing new style”. This will give you a single file to download, gmapsupp.img, which you put in the Garmin folder on the micro SD card. If the Russia maps already on the GPS overlap they will need to be disabled.
I have a Zumo 660 and OSM maps work well.
Cheers,
Peter.
Per Beddist’s suggestion, I’m reposting a question here about using Lambertus’s Garmin maps on my Garmin Quest. Here’s my orginal post:
So it was suggested that I try searching for some of the same addresses on the OSM site, which I did, and I found them… well, at least last Friday I did. The OSM site map doesn’t seem to want to find specific addresses today. (Is that a common problem on OSM?)
Anyway, I’d like to know this: If I can find a specific address on the OSM site map, should I be able to find them in MapSource (and hopefully on my GPS) using maps downloaded from garmin.openstreetmap.nl? Just trying to determine if I can extend the life of my old Quest (which works fine except for the old Garmin maps).
Thank you!
Whoa, a blast from the past. I bought one of those 2nd hand in the UAE and used it on my bike trip until Thailand.
You said it. I found that using a Garmin city map the CPU was too slow to auto-route. Unless you want to display the map only and not use routing I strongly suggest you use the Nuvi or perhaps shell out for a low-end Zumo. Nuvi 500 can probably be found 2nd hand and is waterproof.
Splitter is used to split OSM data, not Garmin maps.
To produce my own ad-hoc maps I download OSM data with JOSM and the alternate download plugin. I have the mkgmap configuration files that ligfietser and I have developed for Lambertus’ new style and a batch file that starts the compilation. I just drop an OSM file onto the batch file and that gives me a bunch of files which I can then install into Mapsource, from where they can be loaded into the GPS. It’s fiddly and longwinded to set up, but now it’s almost drag and drop.
Are you sure the tiles from the site won’t fit into your GPS V?
Cheers,
Peter.
Only if the specific housenumber is also given on OSM, you should be able to find it in Mapsource (but no guarantee that it works, the housenumber search is still experimental).
For the Netherlands it’s a different case, all addresses from the Dutch BAG database are added to the OSM data, so there you are able to find more addresses than are added to OSM. Maybe in other countries such open datasets are also available, so if anyone know such source and can convert it to xml / osm format it can be added too.
Thank you for your reply, ligfietser. I’ve downloaded a two custom map files (using selected tiles) and cannot get either of them to find specific street numbers in MapSource, although I can find the same addresses on openstreetmap.org. I suppose that the street number data just isn’t being included in the maps or isn’t recognized by MapSource.
If there is something else I should be trying to make this work, I’d appreciate any suggestions. Otherwise I will just try periodically and hope that this glitch is fixed one day.
One the plus side, I did make some edits to the OSM map regarding my town and neighborhood, so hopefully that helps!
Your help and editing is appreciated!
Can you give an example of an address that you can find on OSM but not in Mapsource?
Yes. 5312 Olde Towne Rd, Westmoreland, The Hamlet, James City County, Virginia, 23188, United States of America
I’m not sure where “The Hamlet” comes from. Not a location identifier known to me. I noticed a similar name in the address for my home, too. The “Westmoreland” part of the address is the neighborhood across the street from the fire station, but has nothing to do with the address in question. Which objects in the OSM maps would account for these?
This is a fire station in our area, as an example. But my OSM maps cover from Virginia to Wisconsin (for a trip I’m planning), and I cannot find ANY street numbers I search for in MapSource. I use the Garmin maps and street numbers work fine, although the map is from 2009.
I don’t know where Nominatim gets this number from. It is NOT in the OSM data. If you click the search result Nominatim will show you more details. The Hamlet is a node on the other side of the highway.
There appears to be more to addressing than what is described in the wiki about house numbers.
Westmoreland is also a place node, which lies the closest to that address: http://www.openstreetmap.org/browse/node/2293771791
It seems there are no housenumbers at all on the OSM.org map, otherwise you have to see the numbers.
Maybe Nominatim uses an external database. Another thing that the Garmin OSM map needs is district or city boundaries to lookup in which city this street is located.
If nothing is found, it starts guessing which place node is the nearest, resulting in those errors.
If you want good address search, you need to import those city boundaries into the map as well as housenumbers, otherwise the map is pretty useless.
So you better use the old City Navigator for address search or wait until someone has imported that data.
In the USA, Nominatim also uses TIGER address data. See this question, and answer: https://help.openstreetmap.org/questions/12150/missing-house-numbers-in-local-nominatim-instance
I presume that’s where it finds that house number.
Thanks Vclaw. How accurate are these data? Can we import this Tiger address data and convert it to osm format to be added to the OSM data (I mean for the garmin generic maps, not to the osm database)? Any ideas?
That explains it. The data is in Nominatim, but not the OSM database. The Garmkin maps contain only OSM data.
Except for the Netherlands, we added address data from the Dutch Cadastre to the OSM extract to improve address search and I could imagine this could also be done with the US Tiger data. So any help to deliver such address data in osm format would be appreciated.
Thanks, everyone. The address data on the OSM site coming from a separate source (Nominatim) would certainly explain why the address data isn’t available in the Garmin extracts I have. I was going to load the OSM maps into my Garmin Quest, just to see if street numbers worked (even though they don’t in MapSource), but I’m now fairly certain that they won’t.
Yes, it would be nice if the TIGER address data could be included with the Garmin maps, but that’s way over my head. Does anyone know how feasible that is?
I’m willing to keep my Quest on life support if it seems like something that can be done, but if not, I’ll eventually have to pull the plug on it, depending on how many more streets and neighborhoods that I search for and it cannot find with it’s 2009 maps. Sooner or later it’s not going to be worth keeping.
Thank you, again!
