FireFox58 Reviewed by FireFox58 on 30th January 2019. Universal Firmware Patcher for Protected Garmin Devices Universal Firmware Patcher for Protected Garmin Devices v.1.10 This is an universal firmware patcher for protected Garmin devices. Many devices recently have a strong firmware protection and cannot use unlocked maps because firmware requires .gma and has MSV ( Map Signature Verification). In this list (http://www78.zippyshare.com/v/CWAOqHso/file.html) you will be able to check if your device firmware requires this patcher or if it just needs gingunlock+mapsigpatch or simply an .unl file Rating: 5

Hi Firefox,
Package successfully loaded and patched 380GCD copied to system folder
All looks good, will try routing in a few weeks when back in Thailand
Thank you for your help

Will give more feedback if 380 firmware works in Drive51 using Thai CN Navigator 2018.20, good for info for anyone else

@FireFox58
Thank you for your prompt reply.

Now my GPS can see the unlocked map and positioning correct on the map.

But I have very same problem as user Baksider about routing on the unlocked map.

I can simulating the routing (turn on GPS Simulator) on the original US Map.
But cannot simulating the routing on the unlocked Local Map.

Look like I also need to rool back to older firmware as 5.40 too.

Would you please custom another SD flask Kit to patched the firmware back to version 5.40

Thanks in advance.

Wow Thanks A Lot .. Very Helpful.. Succeded in Patching my Unit Driveassist 50

One Question - My unit bought in USA with USA Lifetime Map and I'm actually living in Malaysia - Is It any trick to get the unit to update to Malaysian map instead of USA map?

Regards
Nick
