Update maps from Openstreetmaps.

Former Member
Former Member over 8 years ago
Good evening.

When I first got my 520 I updated my maps with more detail as recommended by dc rainmakers site using the openstreetmaps website. Cause the hard drive on the 520 is not massive you unable to have a
large area of detailed maps so I've got my local area of about 100miles radius.

My question is, I'm off to the Alps to ride the Etape in July and ride for a week after to enjoy some real
Mountains. I'm I able to add the section of the alps to my 520 along side my current maps or will I
Need to delete my local maps and download the alps section before I leave?

Thanks for any info.

Steve.

    You will need to delete it as the 520 only supports one file name for its map file. The install is really a hack as the 520 does not support additional maps. You are fooling it by using the base map name for your map.

    There are also different map formats that you could try which creates files that are smaller (hence allows you to add map area). Here is a link that explains it a bit more. http://extract.bbbike.org/extract.html I have been using garmin cycle format which allows me to load a single map from Oregon to Vancouver (which I couldn't do with OSM map.
    Device will still only support one map file (as far as I know). Best of luck.

    Note: I started with DCRainmaker's instructions, but then found bbbike which generates maps in minutes. So far, so good.

    The "OnRoad" format from BBBIKE is highly recommended, I have been using this for 6 months and the file size is much smaller ( or you can have a map of a much larger area) . If you are riding mostly on roads then you don't miss any detail, the things that are excluded appear to be ground cover type shading, points of interest ( eg coffee shops) and street names which makes the map much clearer, less cluttered and easier to view anyway. The map file size for my area is about 25% of the equivalent normal, eg cycle, format

    Which onroads map format do you use? The UTF-8 or ASCII?

    "Which onroads map format do you use? The UTF-8 or ASCII?"

    ASCII, some Garmins still have problems with UTF-8

    Thanks all! Have struggled trying to use the OSM site and map downloads - will give your suggestion of BBBike a try....

    After MANY attempts, I found this page, which finally helped. I used http://extract.bbbike.org/extract.html with the "OnRoad" - Latin1 format (they no longer refer to it as ASCII for some reason) and it's working for me.

    Just so that if in case some one stumbles over to this discussion, https://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download has links to some of the latest and updated places to download the maps from. Like in my case, the maps for India was as recently updated as 13 Mar 22 in one of the website. However, for the Edge 520 Plus, the file has to be renamed to "gmapsupp.img". 

    In case some one finds that there are missing features like road or POI etc, it is request to please update the same on the cycle map in OpenStreetMap. It'll help us all cyclists as a global community.

    Happy Pedalling.
