BaseCamp software version 4.7.*

IT WORKS - You can upgrade to Basecamp 4.7.2. (PC version) and Mapinstall 4.2.2. (that comes with the upgrade) - they do work!

I have seen several warnings about upgrading to BC 4.7.0, 4.7.1 and 4.7.2. Mostly the reason to not upgrade to 4.7.0 is the fact, that the link to Google Earth is removed from BC, so you can not use "view in Google Earth" from within BC. That is just a small problem to overcome - you can save your route/track from BC in KML file format - and import the file to Google Earth - and boom you are running again - Google Earth is showing the route and you can fly the route in low altitude to check for tarmac and not gravel and so on.

BC 4.7.2 can be patched without any problems with Garmin.basecamp.(universal.patcher)-patch.exe (if you shut of your antivirus - it will interfere).
As far as I understand - we are patching BC because it then can work with maps that are not bought from Garmin. The way I fix downloaded maps is with UnLock MapSource Directory v5.2 (unlock mapsource.exe) - and if your are using this way of unlocking maps - you do not need to patch BC. The maps is unlockable -and BC just works.

Mapinstall 4.2.0, 4.2.1 and 4.2.2. is being reported as having a fault (e.g. here :

), where only the overview map is transferred from your PC to a device. THAT IS NOT TRUE. I have tested with both 4.2.1 and 4.2.2 it works fine. The detailed map is being transferred to a well functioning image file - and device works fine.

However - if you want to transfer the image file from Mapinstall to your harddrive (because it is faster) - you need a patched version. The only version patched so far - that can transfer image files to hdd is ver 4.0.4.
If using 4.2.0, 4.2.1 or 4.2.2 the image file can only be transferred to a recognized device - takes longer time - but it works.
I have seen a patch for version 4.2.0 - the patch works but still no possibility to transfer directly to the hdd.

You can manually uninstall mapinstall - just delete the files with in the installation folder - and reinstall the version of mapinstall you want - it will not interfer with BC at all because it is two separate products. All the versions can be downloaded from Garmin - a bit tricky to find - you have to google it.
If you want to download mapinstall 4.0.4 patched links can be found in this forum.

I have asked Garmin over the last 3 weeks - does mapinstall 4.2.0 and newer works or does it fail transferring maps data. They have tested several times - Mapinstall 4.2.2. works fine!
Time to kill the bad rep BC and Mapinstall have - it works - but you have to understand the differences.
