Map signatures are a digital signature that is written to the map files that Garmin produces.

On devices that support reading map signatures, any map that has been altered and does not pass the signature test will not be opened.

And only new devices read these Map Signatures ??? well we go back to post #8 ???

maybe need be carefull with another old devices also, when new firmware coming ????

Authentically:
Device support is still ongoing – release TBD ...
