Can't authenticate maps. Contact seller... Solved

The problem: I have an Etrex30x ver3.0. Up now I have always downloaded map tiles from garmin.openstreetmap.nl, installed them in Mapsource and used Mapsource to send the map to the Etrex. No problem. Recently I tried to get a current map from download.bbbike.org but the site provides only pre-compiled gmapsupp files that the etrex rejects with the message 'can't authenticate maps. contact . . .'

My solution:  a) split the gmapsupp with the 'Split' option in Gmaptool (*see link below for instructions) and b) install the resulting *.img files using MapsetToolKit. At this point I can open Mapsource and carry on as usual. Problem solved.

Software needed:
1. Gmaptool.exe http://www.gmaptool.eu/en
2. cgpsmapper.exe https://www.gpsfiledepot.com/tools/cgpsmapper.php (used with Gmaptool)
3. MapsetToolKit.exe https://sites.google.com/site/cypherman1
-- with linux it works perfectly using wine

This process probably works with other devices that use similar firmware:
Oregon 700/750, Edge 520/820/1000, Etrex 20x, Etrex Touch 25/35, GPS Map 64, Montana 610, 680 . . .

Hope this helps

I just found a much better solution. Just reinstalling the firmware does it. I used MapInstall ver.4.2.3

Obviously unicode maps still trigger 'Can't authenticate...' but that's a different issue.
