How to fix java,registry and memory problems
Java
Go Help,Download Essential Software
Click on Download Java and download Java from website
Note: Once downloaded, you need to restart mapuploader5 - no need to reboot PC !
Memory
Large OSM files need to be split to avoid memory issues
- We suggest splitting the osm using a maxnodes value of 80 000 or even 40 000
- Eventhough your PC comes with say 16gig memory the Java VM only works if memory is set to
-Xmx1024m
You could try -XMx 2048 but more than likely java will bomb out!
- If max-jobs are not specified mkgmap often produces the wrong value! , ie max-jobs=8
We suggest you start with max-jobs=1 : Go Preference,Setup,Advanced
- Another suggestion ,put forward by one of our users, who had serious problems compiling a 5gig map:
download an older version of Java, jre-10.0.2_windows-x64_bin.exe
It solved all his problems with no limitations to max jobs!
Registry
On W10 there may be a problem accessing the registry when uploading to Basecamp/Mapsource
- Go Tools,Fix Registry Problem
- Click OK to install a test map.
- The default destination folder is C:\Garmin\Maps\test-map
- Note : make sure mapuploader's map target folder is the same:
Go Preference,Setup,Essential
Check your map target folder and change it if necessary.
