I have a GPS map on my computer in the form of a 2.3Gb .img file. I read that I can put that directly on a SD card and the GPS can read it.


I have a USB cable plugged into the back of my computer 3.0 ports and into my GPS with a 4Gb SD card installed as drive N:. I dragged the .img file to drive N: and the transfer rate is about 335Kb/s. Is that what I should expect?



Can't keep up with the computer stuff anymore. It's getting beyond me.  :mellow:

FWIW:  General observation that I have made...when transferring files from system-attachedd-drive to small media  (.mp3 player, flash drive), the transfer rate seems to be bottlenecked by the size of the media.  The transfer rate from the media to the system is much faster.
