I have downloaded and unzipped the 2 Topoactive Europe 2019.20 files using lastest Winrar but when I copy to to the Garmin folder of my SD card in Garmin Etrex 30x I get the message - "Cannot Authenticate Maps".
I don't usually have any problems so I'm guessing they are still locked although they will open in Basecamp.
I have tried unlocking with gimgunlock-0.04 and Garmin Unlocker Alternative 7.1.6 but no success.
Can you tell me where I'm going wrong please?
Thank you.

Etrex 30x would have answered your question.
Look in your garmindevice.xml and confirm your HWID is 2250
eTrex 20x/30x | 2250 | 290 | MAP: Yes | GMA: Yes | MSV: Weak | GVS: --- | File: eTrex20x_30x_Webupdater__490.gcd
MSV: Weak - it verifies the validity of map signatures in a simple way, you can unlock an .img using gimgunlock-0.04 (without patching your
firmware), but in case of unicode maps (CP65001) you must modify the CP value (see the Temporary authentication of Unicode maps*).
