My TomTom GO 500 formatted memory card is not recognized by TomTom Connect
I downloaded a map update to my sat nav expecting it to save on the SD card but it found space on the internal memory to save the update. There was 4 MB memory remaining on the device. I tried downloading a voice of 66 MB as a test to see if anything saved to the SD card but TT Connect didn't recognise that the memory card had been formatted. I had the option of deleting some items or formatting the card.
Checking the device under Settings it showed it was formatted for use on Tom Tom.
When I check the content on TT Connect, the card is visible but only a fraction of the memory has been used, I presume by the formatting.
What is going on and how can I save to the SD card.
