Re: Universal Firmware Patcher for Protected Garmin Devices

Please, I have a Drivesmart 66. I have a 32G microsd card. I loaded some unlocked maps using "Mapinstall", but when I turn on the Garmin, it says the maps are corrupted. Do I need a firmware patcher? If so, is there a currently working link and clear instructions?. I downloaded something above called "nuvi 25x9 (1758) fw 8.80.rar" but I don't know it's right nor what to do with it. I'm very confused and a lot seems quite outdated. I also have a Nuvi 3950- would that be easier? Thank you.

Hello, I think it's the same situation as 55 65 76 86 | of the new Garmin devices, at the moment there is no solution.

Welcome to the forum.
gajevi52 is correct your DriveSmart 66 has encrypted Firmware .
Firstly no other firmware patched or not will work unless you need a "Brick"
I assume you mean a nüvi 3590 ,the way you find out if a device need patching is to look inside the garmindevice.xml for the HWID
<PartNumber>006-B1258-00</PartNumber>
<SoftwareVersion>850</SoftwareVersion>
<Description>nüvi 3590</Description>
</Model>
Then search this topic using your HWID
If it is 1258 it does not need patching

Thanks a lot. Giving up on the Drivesmart 66. It looks like the Nüvi 3590 is going to work.
