I have a Nuvi 500 and I am trying to use OSM maps that are on a micro SD card (2GB).On the SD card,I made a folder "Garmin." Then I copied a "gmapsupp.img" file (619,264 KB) inside the Garmin folder.Then I went to tools,settings,map,map info on the Nuvi.2 maps are selected.OSM generic routable (I think this is the one I just put on the SD card.) And OSM map (1) OSM World Routable (63241144), OSM World ... I think this is a map that someone installed for me 2 years ago.It is a basic map with main roads.I am going to Europe Monday and need more detailed maps.When I zoom into Barcelona,I only see 2 or 3 roads. In my Nuvi built in memory,in the Garmin folder,are about 25 files.Below I am listing some of the larger ones.
This is one I probably tried to install 2 years ago while in South America.I didn't work-just had the world map detail. I just don't know what I'm doing wrong.I've read directions several places and nothing has worked.Hopefully someone can see my error and help me.Thanks. |
I'm guessing that you've confused it by giving it more than one gmapsupp.img **. Before doing anything else though - TAKE A BACKUP! (so that if you delete anything that you shouldn't have, you can restore it). If it helps, here's what's in the "Garmin" directory on the main memory of my Nuvi:
And here's what's on the "Garmin" directory on the SD Card:
I believe that the "Ecuador gmapsupp.img", "gmapsupp.img" and "gmapsupp.img.img" that you have in the main memory are the ones that you want to get rid of. I don't know what "gmapprom1.img" is, so I wouldn't delete that (although I suspect it might be a from-Garmin update to ther map). ** Newer Garmin models do support multiple supplementary maps I believe - but I doubt yours does. answered 30 Aug '12, 17:02 SomeoneElse ♦ I deleted the "Ecuador gmapsupp.img and the "gmapsupp.img.img". Nothing seems any different. My SD card has gmapsupp.img in the Garmin file.Nothing else-unlike yours.

The osmmap.tdb and osmmap.img are optional - you don't need those. Have you still got a gmapsupp.img in the device memory AND on the SD card? If so, you shouldn't have.

I deleted the gmapsupp.img on the Garmin memory.After doing that,my OSM World Routable selection is missing in "map info".But the maps in Europe seem to be the same as before-basic. I took my SD card out,and Europe still looks the same.The OSM routable isn't in the "map info" anymore.

I have maps on my GPS now.I downloaded the maps again-same files.And now they work.The only other thing that is different is that I used a different program to unzip. Quick Zip. I'm a happy traveler again.

I've been using a recent talkytoaster OSM GB map on a Nuvi 2460LMT for the last couple of weeks. Seems to be going OK for routing using imported destinations other than a couple of mapping errors - now corrected.. Today I drove home without setting destination and many minor roads didn't show at all - arrow on empty screen but road names were shown at the top. I've not taken much notice of roads underlying routes but there may be an issue here. Do you have map detail set appropriately? answered 30 Aug '12, 17:03 fruit-uk I've seen the "minor roads don't show" effect, but think that it's a different issue to what the questioner reported. If you're following a Nuvi down a long minor road it will tend not to show the minor road network around where you are unless you zoom in. I suspect that what's happening is that the standard maps from Garmin will tend to have much less detail than OSM-generated maps (although it depends on how you setup mkgmap, of course) and therefore the "zoomed out overview" makes sense in that context.
