hi
is there an easy way to back up the sd card with the nissan nav on it i have tried to do it on my pc
but it has taken 11hrs plus to do less than 3/4's of it

thanks for any advice

In a word, no.

The software on the card is locked to the SD card unique serial number. The data is also encrypted.

If you did a bit by bit clone, then it will not work as the serial number will be different.

i always like to plan for the unexpected , i wanted to make a backup of the card and if it ever became corrupt i could
format the sd card and then put the software back on it.
that was the thinking behind it
thanks for your help
