How long should my NB1 SanDisk take to update?

I have an NB1 Mazda Navigation SD card that hasn’t been updated for 7 years. It is stuck on update “3. Downloading Map Share corrections” - been running now for about 20 hours!

I can see in task manager there appear to be packets of data being written to the SD Card, but very slowly, and even given the long time since the last update the time it’s taking seems excessive.

Anyone able to advise if this is normal or if I should abandon?
