Hi!
New user here, searched everywhere, couldn't find a valid link to the universal patcher, nor the sd card files to unlock Garmin Driveassist 51

<PartNumber>006-B2590-00</PartNumber>
<SoftwareVersion>310</SoftwareVersion>
<Description>Garmin DriveAssist 51</Description>

Does any of you have that files and are willing to update to valid server?
Thank you very much in advance!

Great, mate! Really appreciate.
Let`s see that I manage to patch my device....I´ll read through the pages and try what I can do as dummy....long time registered, but never new about patching the device as I recently changed to 65s from my old 62s...

Copied the GCD file to SD-card under "/Garmin" and device was updated(down-versioned) to 4.50 and now reads downloaded maps....I guess I did it right ?
Thanks again for the support.
May I ask also to update the link for the patcher ? Just in case for future device change....

Good day, clearly I'm a little late to the party, just bought a 64S to replace my old 60CSX, I have the "cannot unlock maps issue". Is there an active link to this firmware update. I have searched this thread all links are inactive. TIA

Used one of the links on here to go to Garmins official downloader for 64S and although it states Version 6.06 there is no download link.
The only official link I can find is for version 2.58.
Is there a link for the 64s downloader?. TIA

eTrex Touch 25/35 (2140) link updated


Well, I asked, I got it (thnx :-) and i did the patch. It is working (tested with GB Discoverer map).
But after this, I dived in it a little more....

This is my device:
<Model><PartNumber>006-B2140-00</PartNumber>
<SoftwareVersion>452</SoftwareVersion>
<Description>eTrex Touch 25t</Description>


So it is softwareversion 452, i patched with '450'.
Could this give a problem?
Should i patch again with the 452 patch (if/when available)?
