The phrase likely refers to the high regard for GarminCure3.exe , a community-developed third-party tool widely considered the "better" or most reliable method for unbricking Garmin GPS devices .

When a GPS device fails, users typically attempt fixes via official channels like Garmin Express or WebUpdater . While these applications excel at routine map updates and stable firmware patches, they are ineffective against structural file errors.

It creates "CURE" firmwares that bypass the normal booting process. Instead of loading internal system files that might be corrupt, the patched firmware directs the device to enter mass storage mode immediately upon power-up.
