I just got a tomtom one refurb from amazon.com.
Turns out the SD card is corrupted. The unit reboots itself occasionaly and can't calculate routes and has other problems.
I discover there was something wrong with the SD card when I tried to do a backup. The map file, cline.dat couldn't be copied because it is corrupt. I ran chkdsk onthe SD card's file system, and it reported that the file was corrupt, plus other problems. Hopefully, I can get replacement files from customer service. I'm just posting this thread in case others have the same problem.
