Garmin DriveSmart 86 Maps are corrupt

Postby sshenhaby » Sat Jul 26, 2025 12:19 pm

Hello
I am new to the group and have a new Garmin DriveSmart 86 with Europe maps installed. I followed thd guidance here and installed the Middle East maps, but when starting my device it gives the message "Maps are corrupt and cannot be used".
I read in the forum in old posts I may need to patch the device but all linked files are not available and the post is quite old and I do not want to do something wrong with my new device.
Can you please help me with detailed steps and tools to solve my problem as this topic is new to me?
Thank you for help

Welcome to the forum.
I moved the new thread you created to the existing thread covering this.
Unfortunately your device is one of the latest devices that have encrypted firmware and cannot use Unlocked maps

Howdy!

I just added the CN NA NT 2026.2 to my Garmin Montana 680t and noted that there was an issue authenticating the map (first time I have noticed this) - I did a bit of digging on the forum and found this thread, but it seems the links are no longer valid for a lot of the tools needed to patch the firmware. I was wondering if someone might have gone through the same thing I have recently, and would have the updated information? The map does load in basecamp when I have the device plugged in, but it does not show when i boot up the device.

Edit for device info:

<PartNumber>006-B2299-00</PartNumber>
<SoftwareVersion>350</SoftwareVersion>
<Description>Montana 680t</Description>

Thanks for your time!

Normally you would not need to Patch your device with NT maps. Maybe try removing the map you have and download a Regional map to test if the error is from the NA maps
