I concur, I always stack OSM maps with other maps when avaliable and a 276c/478 is the only gps out there:funmeteryes:I love collecting maps for my garmin makes it even more fun:scooter:

Do you ever find that when stacking maps, sometimes when I zoom in or out, I briefly see a road or river that is not showing, and by switching of maps they appear. Can you and how, set the transparency? Or how does it choose which map is the top layer?

You can adjust the sensitivity of your gps to the highest setting and that can help but mainly causes more clutter in my experience. Most maps need to be zoomed in to </=0.3miles to have full detail, that's why I like running two Gps units with same maps loaded, usually a handheld powered 76c and a 276c/478 then you have the best of both worlds wihtout jockeying the zoom all the time, one macro, and one set micro for the detail. Some countries the osm is better and I will turn the local map off or viseversa but its great to have both because the both come in handy usually one is better than the other in rural vs urban.

waypoints to match
 

if you're installing maps for central or south america then you may have a desire for some current waypoints.
I'm travelling 4x4 so not 'exactly' motorbike based but none the less handy i reckon!

check my homepages .. . . . .

navigate to the 'coming this way' link, then just 'elp yourself.

I wasn't referring to the sensitivity, but to the transparency. I have the OSM map for Suriname installed, and the world map as well. When I scroll the map, sometimes I see a road appear for just a second then its gone. So I switch off the OSM map and there is the road in the world map. So my question is: how does that work. In other maps if there isn't a road, I believe it will show the world map road?

Not sure what causes one map to supercede the other. I play with the mapset that works best in the location I'm in and turn the other off and don't run into that problem. In my expereince one map works better in the countryside and the other better in urban setting, takes a little swapping of the buttons but still nice to have access to more than one. I also like to compare to google earth view my tracks or proposed routes on mapsource in GE when I'm around wifi.

I was looking at taking the jungle loop in Suriname, only big loop of a road that dumps out at the river a little ways up from the coast at the Suriname/Guyana border. You staying along the coast? Did you get to see a rocket launch in FG if headed that way I would do my best to attempt to view, they are very impressive.

I would love to be able to import google earth maps or even download the cache on the mac, but I don't seem to be able to do just that for now.

Suriname: We are in contact with the SARK, [Surinames Auto Rally Klub] and have been "competing" in two rally's so far, with the big Savanne rally coming up in november. So we are experiencing some real jungle off-road tracks with the cracks!

Map stacking
 

If you have multiple maps loaded on your GPS, you can only see "the one on the top of the stack." The maps' priority (where they fit in the stack) is built in when the map is constructed. Very few maps are actually built to be transparent, so if you are looking at one, it is hiding the ones underneath. Sometimes you see a flash of the other maps when the GPS is redrawing the display. The only way to see maps underneath is to turn off the ones on top. You can not adjust the map's transparency (unless you are the one building the map).

On my GPS (Garmin GPSMap 276C), the order that the maps appear in the Map Information list is generally the order that they stack.

In any case, redraw is fastest when only one map is turned on at a time.

Hope this makes sense.

Great info Laura! That is what I was looking for.

Bolivia Maps
 

We now have quite a few choices for Bolivia GPS maps.
1) Proyecto Mapear (ok, but limited coverage in places)
2) Open Street Maps (very basic)
3) Bolirut Bolirut (free and quite good)
2) RutaBo ruta-bo (US$26 and the best map available)

By the way, the Ecuador Maps at proyectoecuador are terrible. They have not been updated since 2011, and they weren't worth downloading then. For Ecuador, I use Open Street Maps. Same solution for the Guyanas and Surinam.

For Chile, the most recent version of Proyecto Mapear is quite good. It finally has many POIs on it for Chile, in the past it only had the roads in Chile.

Best South America Mapset
 

As i posted a few years ago in a different thread, there are some excellent maps available if you spend the time to combine a number of them. Here is the mapset i currently recommend:

Canada/USA- Garmin City Navigator North America
CentralAm - CenRut
Colombia - Colrut
Venezuela - VenRut
Brasil - Tracksource
Uruguay, Argentina, Chile, Paraguay - Mapear Proyecto Mapear
Peru - Perut
Bolivia - RutaBo
Ecuador,Suriname, Fr.Guyana, Guyana - Open Street Maps

Here is what i recommend about making the mapset:
1) combine all the maps in MapSource into a single mapset and install on your device
2) In device setting there is 'Map', and on "Map', there is 'Info'. In here you can select/deselect certain components of the overall mapset. By deselecting all the components except for the one i want to see, then I don't have any issues with map stacking or overlapping (which is a real problem). Change select/deselect depending on where you are and what map you think is best suited for where you are.

I just downloade the OSM map for Bolivia and the Bolirut, and I must say I am impressed with the details of the OSM map, especially outside the cities.
Between the two, OSM is my favorite.

Can't say anything on the RutaBo...
