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.
