Warning: do not update Basecamp! [Solved]

It took me about an hour to find the link for the Mapinstall file. Garmin still hosts it online.

http://www8.garmin.com/software/MapInstall_404.exe

Find the temporary folder where the Basecamp update is stored. On Win7 it’ll be C:\Users[youraccountname]\AppData\Local\Temp\Garmin Software Updates

Delete everything inside Garmin Software Updates folder, then right-click on this folder, choose Properties, then **Security **and finally click Edit.

For all user groups in the list check Deny box in Full Control row below. Then Apply, Yes, OK, OK. That worked for me.

Does Basecamp 4.8.4 still have this problem?

Bob, 4.8.4 is the Mac version, this issue concerns the maps that are installed under Windows (to be precise: only those maps that are registered in the windows registry with an installer or .exe file) . So AFAIK no problems on Mac OSX.
There are also no issues if you run the latest Basecamp/Mapinstaller with the gmap versions (the so called Mac version on garmin.openstreetmap.nl, but those can be used on Windows computers as well).

Hi ligfietser, thanks for the speedy reply. However a couple of years ago I downgraded to a 4.7 version of Basecamp in order to load some OSM maps onto my Garmin GPS. However last year I bought a new Mac and without thinking added the 4.8.4 version of Basecamp to it. Yesterday I found it impossible to transfer a downloaded OSM map of Italy (I’m off there on Thursday) from Basecamp to my Garmin Montana. So I assumed it was the old problem, but perhaps I was doing something else wrong then? Any tips?
Best wishes,

Bob

You can always check with Javawa Device Manager if there is something wrong.

Other possible issue is a not compatible format of the micro SD card (must be <64Gb and formatted as Fat32). The Mac’s internal programm for formatting the Sd cards is also not compatible with Garmin devices.

You can also try to copy an already prepared img map directly to the device’s garmin folder with a file manager without the need of Basecamp.

It is also recommended not to use the Basecamp version from the Mac App store but download it directly from the Garmin site:

Many thanks. I’ll give these things a go.

Feel free to report your findings here, it might help other people with the same issues!

It seems, the MapInstall software version 4.2.1 (October 30, 2019) works correctly, so it is possible to update Basecamp to version 4.7.1.

Thanks for noticing zhrd, it seems that Garmin finally has solved it!

Thanks, this works. Basecamp doesn’t nag anymore about updates.
