    I'm looking to install maps on a garmin 76csx. I've found a site open chest maps which has maps for download hat can be used in garmin units. Has anyone used any of these? Any feedback would be great.

    Thanks

    Do you mean Open Source Maps, (OSM). I have downloaded and successfully used these for UK, NY, Pa as well as Ontario. They work well on my Oregon 600, routing is customiseable. I think they are a reasonable alternative to the wildly overpriced Garmin maps. I do not like the map colours, they seem to be night colours and are not so visible in daylight. That being said I still prefer my Backroads Mapbook as it has more detail. I am sure Bob will be along to to give you the experts opinion. I have attached a screen grab of the Creemore area OSM Creemore.jpg

    At the risk of hijacking this thread (since you mentioned the backroads map), does anyone know of a way to be able to see the backroads map trails, etc when the GPS view (in this case the Montana 600) is set for greater than 300m? Once I zoom out past 300m, all the backroads details disappear. At minimum, I'd like to be able to see them when I'm zoomed out to 500m, 1k...

    Alon,

    Make sure your detail is set to "most" in the map setup subpage.

    Mine is set at "most" and I can see all the trails, road allowances etc, even up to 1.2km zoom level

    I'm pretty sure I have that set already - will double check. You can see the green, orange, etc trails when zoomed out past 300 metres of resolution?

    Absolutely. Looking at Bruce Trail and ODSC trails as we speak.

    That was the advantage of some of the older Garmin maps.. Compared to some of the newer Garmin maps.. Where if you zoom out too far and almost everything disappears (except for example Hwy #6 and Hwy #401).. As mentioned that way when you zoom out example 500m you can still see smaller hiways and secondary roads and be able to see if you are headed the right way.. You will have to "toggle" back and forth from example MetroGuide North America V6 to Topo Canada V2 to MetroGuide Canada V4 but at least it can be done when viewed on your computer screen (see below pics) or your gps while enroute (sorry too lazy to do gps screenshots but same principal).. As mentioned you will have to set detail to "most or highest". . Cheers

    P.S. I sent Chef (Kevin) some of my older Garmin CDs (titles above).. He can then upload them to his laptop and he will soon be a Garmin map expert as well when guiding you guys on your dual sport rides.. Be nice and ask Chef to bring the CDs to the ride and bring your own laptop and upload the CDs to your own laptop also (these are shareable Garmin maps that don't need a un-lock code)..

    This pic is the newer Garmin City Navigator North America V8.. This is locked software and needs a un-lock code (it cannot be shared).. At 20km and highest as you can see no details around Flesherton, Ontario..

    This pic is exact same spot but I "toggled" the map on my computer (gps is similar) to the older Garmin MetroGuide Canada V4. . This is "UNLOCKED" software and needs no un-lock codes and "CAN" be shared. . At 20km and highest as you can see much more details around Flesherton, Ontario.. If you need more detail zoom in on your gps or laptop..

    This pic is exact same spot again but I "toggled" the map on my computer (gps is similar) to the older Garmin Topo Canada V2.. This is also "UNLOCKED" software and needs no un-lock codes and "CAN" also be shared.. At 20km and highest as you can see yet even more details around Flesherton, Ontario.. If you need even more detail zoom in on your gps or laptop..

    Good info,

    I think the op was asking about Open Street maps, perhaps we will hear from him

    It was actually open map chest. I'm waiting for Tony's cd to arrive and going to try to load it on a sd card and install on the gps which has nothing on it.

    Seems like they are almost the same thing. The data is from the OpenStreetMap (OSM) project and is compiled with "mkgmap", so they might perform slightly differently, depending on the specific settings used, compared with another OSM Garmin map.

    The OSM website only seems to provide raw data. Maps for use in Garmin GPS must be compiled and there are several different compilers - the one I use for my map making is cGPSmapper. So, to compare OpenChestMaps to "OpenStreetMaps" you really need to know both which compiler was used and (most importantly) what settings were used.

    You can find out the compiler by opening the map in Mapsource and then using the "Manage Map Products" under the Utilities menu. My OSM maps show this info:

    but I doubt you'll find out the settings - you'd need to run the Map in Mapsource (or BaseCamp or your GPS) and check the detail is what you need and it appears at suitable zoom settings (the main settings I change from map to map).

    I downloaded and installed the OpenChestMap for Canada and it seems very similar to other OSM maps I have.

    It does show the most minor roads out to the 3Km zoom, compared with Garmin City Navigator, but the GPS screen is very cluttered, It's slightly better if you turn OFF the Land Cover setting in Setup Map / Advanced Setup / Zoom Levels as this turns OFF all the green patches (Forest?) that seem quite unnecessary. For a FREE map it seems good, but I haven't used it for navigation and cannot tell if it's POI database and Routing algorythms are as good (bad?) as Garmin's.

    The downloaded IMG file isn't "locked" so you can open it in an Editor (I use GPSMapEdit) and edit the settings if you want it to perform differently.
