I have Drive Assist 50 LMT-D with the following installed when it was purchased.
CN EUROPE NTU 2021.10 FOURSQUARE
CN EUROPE NTU 2021.10 UK |& IRELAND

So I wanted to update the European Map to 2021..
The install completed , but when I boot the Garmin - on startup I get "Maps are corrupt and cannot be used"

Firstly your device uses NTU maps for Europe.
Check & confirm your HWID is 2270 by looking at your garmindevice.xml

Of course it can go wrong, any software update can.
Why do you want to patch, what maps are you trying to use ?
GPSMAP 66 | 3028 | 210 | MAP: Yes | GMA: Yes | MSV: Weak | GVS: --- | File:
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*).

Welcome to the forum.
Your device will need to be patched to use unlocked maps. First check your garmindevice.xml to confirm your HWID is 2586

Thank you.
I want to use Topo Pro Maps (for hiking) like I have on my 62stc. That one is going for sale now.
I have tried to install those maps on my 66s but it won't accept. Can't verify.
I have tried to unlock some with gimgunlock- 0.03 but that doesn't work. I did not have version 0.04. Now I have. So I can give that a try.
Otherwise I might going to give OSM a try.

1. Patching allows you to use other Unlocked maps that are shared here. Garmin Express will only update maps you have a LifeTime subscription for (Central Europe for you)
2. Yes you could reinstall the original Firmware (Not Patched) but then you would not be able to use Unlocked maps, not sure why you would do this.

Hello everybody! Yesterday i friend gave me his new Alpha 100 Unit. I show in the information menu version 7.90. Will we be able to patch that version? Also anyone knows where to find the version in order to patch the device? (the garmin site does not have any information and files to download.they still have the 7.80 version [Please Register or Login to download file] )

Not the first "New" device I've come across displaying the next FW version.
Check the device for the GUPDATE.GCD and share it here.

Good evening gentlemen, I am Sandra and new to the Forum.
After reading and collecting a lot of information presented here, I unlocked my GPS ... thanks to the help given to others by GarmanNuvi and FireFox58 when they helped other colleagues.

I am going to summarize the steps that I found. For those who have the same GPS, it can be useful without searching everywhere as I did.
