I am looking at this on ebay and I am new here so I am not really sure what to do. I am looking to get my maps updated but do not want to pay $120.
So I came across this on ebay, does anyone know what this does? Is there no difference between the 930 and the 940 besides the firmware?
Thanks in advanced for your input.
