HI
my car comes with with a original Papago M3GPS x8.5 OEM Navigation Software in a SD card, as SD card prompts to get spoil easily so i plan to clone that SD card or copy the contents out from that SD card to another new SD card which will be used as backup.

I have tried many ways such as windows files copy , using some files cloning software but all failed to work, when I insert the clone SD card, my car audio cannot recognize the software and it hung there.

Anyone can help to advice what is the best way to make a backup copy of that original SD card will be much appreciated here, thanks
