Thanks Catymag,

I have tried RMPRepUSB but this program couldn't detect Garmin drive (show 0 drive).
Note: Even I install Garmin USB driver but my PC not show garmin usb drive.
Garmin updater could detect USB when I enter in pre-boot mode only.
For normal, PC and RMPRepUSB couldn't detect USB drive.
Highly appreciated other advice too.

Thanks,

JUR
