Universal Firmware Patcher for Protected Garmin Devices

I just installed "DriveTrack 71 fw 6.30+JNX.rar SD card Kit FWID 2588 ONLY" and same problem, the device only shows the pre-installed jnx maps.

I have tried to copy the JNX maps in both the internal memory and in the SD card with the same result.

Before installing the patch I removed all existing JNX files.

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
