When loading maps I get the Can't Authenticate Maps error on the new 64s device. Allready changed the code page but this doesn't helped. Couldn't fimd a gimgunlock version which works on W10. Anyone can help?
As instructed by others, I downloaded, installed and extracted the latest gimgunlock 0.03+MapSigPatch which can be found here. Drag the locked .img file to the .exe file and let it do its thing. Once unlocked, you can now use the unlocked image file. It works on my Gpsmap 64s and I'm also using Windows 10. Make sure you drag it to the executable file, not double clicking it. Good luck.
