I have a 2 gig sandisk Ultra II. Installed TomTom 6 in its own directory. It works plotting short distances, but I get an error message if it tries to plot a course to a destination more than 30 or 40 miles away. I have defragged the disk. When I use the 1 gig SD that came with TomTom, there is no problem. Is this a format issue, or is it the Sandisk? I assume I can copy the entire disk to my hard drive, format the disk, then copy back to it?
Thanks
