According to TT's site, here, the only restriction seems to be it must be a SD card.
I've wondered about this too. My copy of my SD card is a little over 3GB and I've wondered what the process is to move to a larger card if needed. Do you just copy the card's contents to the larger FAT32 card? That would seem pretty easy.
I'm interested if anyone has done that and if TT does detect/view that as transferring to another device.
Just bought my cx5 on Saturday and I can not get any of my computers to recognize my SD card so I can update the software with Tom Tom home? Sorry this question is off topic, but I did a search and could not find a discussion thread.
Have you looked at this TT page? What you do is dependent on your computer's OS, but this might help you out.
I tried 3 windows 7 computers all aging in range from 1 to 3 years old. I also tried both a built in and external USB card reader. I did try all but the last suggestion from the support site thus far. My camera card reads fine so I am at a loss why the nav card does not read.
I am sure you will have checked the lock switch on the card !! ?
My 2014 GT comes with 8 gig SD card.
