For everyone knowing how to use Mapsource
There are some pecularities with the VeloMap.org to pay attention to: It is not advisable to simply select maps by left clicking if you have contourlines installed. If you have, then you need to select maps by dragging the selection tool while holding down the left mouse button, else you will either send maps without contourlines, or contourlines only to your GPS. If you have not installed contourlines, you can do as you like.
Note the checkbox "Include Route Calculation Data." in the lower left corner. It shouldn't be deactivated – else the maps will be sent nonroutable to your GPS device.
Also note the "Mapset Name" in the lower left corner – for new generation GPS devices, you should set an easy to identify name for the map.
For Newcomers to Mapsource:
Mapsource is the easiest tool to send maps to your GPS. There are some pecularities with the VeloMap.org to pay attention to:
0. Select the VeloMap in the drop-down menu if you have not done so already. The drop down menu is to the left of the "+" and "-" button used to zoom in/out. It is only shown if more than one map is installed.
1. Zoom out (best to 30 – 70km on details "Medium" ). You can directly click onto the zoom using the drop-down menu (in above screenshot still set to 150m).
2. Select the mapselect tool from the tools menu:
3. Now click on the map – and while holding the left mouse button – drag it over the area you wan't to tranfer to your GPS. In the right pane under Maps you should see the selected maps now:
Note that there are maps where inside the bracket a number starting with 6 appears (e.g. 63650000) – those are the map data tiles. Those maps in the Maps field where a 7 is appearing inside the bracket are the contourlines map tiles. If you want to send the maps without contourlines, you could now simply mark and delete them from the list.
If you want to transfer maptiles from several maps, just select another map on the map dropdown menu – untill all maps you want to have on your GPS are selected
Note: maps previously on your GPS in /garmin/gmapsupp.img (basemaps are saved under a different name) will be overwritten, so include maps previously sent to your GPS too if you want to continue working with them).
If the firmware of your GPS is up-to-date most GPS can handle up to 4096MB of maps.
Note you can also click instead of drag with the mapselect tool. However if you have installed contourlines, clicking will leave you with either the contourlines only, or the maps only. So if in doubt, drag with left mouse button, and don't simply click/tick to select maps.
4. Make sure that if you wan't to have autorouting enabled, that this button is ticked:
5.If you have an old generation GPS (see below for explication) now choose any other mapsets that you wan't to transfer to your GPS (different map in step 0 and repeat to here). Notice that by sending new maps to your GPS all old maps (except the basemap, or the Topographic extended map of Europe for some Colorado/Oregon/Dakota that came with your unit) will be deleted/overwritten.
6. In the top Menu click on Transfer –> "Send to Device". It's fastest to send the maps to an SD/microSD card in a card reader because most Garmin units only support USB 1.1 and not USB 2.0 High Speed – so sending maps directly to the unit connected via USB will take much longer than to your data card. I recommend to send maps to external data cards and not GPS internal memory.
Differences between old and new generation Garmin GPS Devices:
old generation GPS devices (Vista, Legend, 60 CSx, edge 705…)
On older generation Garmin GPS devices (e.g. Vista HCx, Gpsmaps 60 CSx, edge 705) you can only send 1 map compilation called GMAPSUPP.IMG
This means you need to send all maps at once to the GPS/memory card, maps (except basemap) previously sent will be overwritten. If you want to be able to switch the contourlines on/off on your GPS device, best install it as a separate map in Mapsource/Basecamp, then select first the normal map and delete all 7* (e.g. (73650000)) from the list on the left hand side, and then select the map tiles from the contourlines only VeloMap.
new generation GPS devices (Oregon, Dakota, Colorado, etrex x0, 62series, edge 800 …)
All maps sent at once will appear as one map on your map selection setup on the GPS device. If you want to be able to switch maps on/off separately, then send them once, and rename the GMAPSUPP.IMG into anything else (well the .IMG needs to stay) – but don't use Umlauts, special symbols or spaces in the name. Then just sent the next map. This makes it very easy to manage your maps. You can simply export map by map and rename it. If you want to upload a new updated map, delete the old map you previously sent, and send only the new map again.
Sending Maps with Basecamp/Mapinstall to your Garmin GPS device:
Note that sending maps with Mapsource offers you more options. But if you don't have Mapsource installed, you can also use Garmin Basecamp (which uses "Mapinstall" to send maps to your GPS).
Please read through the differences between old and new generation GPS devices first and also read through the newcomer guide for Mapsource to get a general understanding of how it works. The main difference is only that Basecmap/Mapinstall offers less options.
1. a) Click on Utilities –> Install Maps (note this is only active if you have connected a GPS device via USB ) – this is not recommended as map transfer will be very slow via USB on many Garmin GPS.
1. b) Insert the memory card of your GPS into a memory card reader, and wait till it is red in in Basecamp. It will show you all previously installed maps (note check if they are called gmapsupp.img – in that case they will be overwritten). Right click the ALL Data folder and click on "Install Maps on ….".
Select all map tiles of the region you are interested in by dragging with your left mouse button clicked over the map. On the right hand side you can see how much space is available. (note this is the only real advantage over Mapsource, which doesn't look for empty space).
If you want to send several maps at once, then change the map with the dropdown on the bottom, and also select the maptiles, once finished click on Next, you'll see another confirmation page, and let Mapinstall send the maps to your GPS/memory card.
