Go400 No longer sees memory card

About a week ago, my wife's Go 400 complained that there were no maps installed and, on further investigation, the memory card was no longer being recognised. I took the card out, and checked it on a PC, which looked fine apart from the fact it said '0 bytes free'. I wondered if this was the cause of the problem, as the Go400 wouldn't be able to write to it. I re-formatted the card, and re-inserted it into the satnav, but nothing I can do will persuade the memory card to be seen. As I can no longer install the maps on the internal memory (not enough space) I'm a bit stuck! Any ideas?

    Hi @nevans

    I would reformat the card again in your PC but not a Quick Format. You really need a 16 or 32gb card for Full Europe. You may be able to squeeze a smaller European map on an. 8gb card.

    Then start the GO400 and insert the Card. If you do not get a message about formatting the card in the unit. Then:-

    Tap menu
    Tap Settings
    Tap System
    Tap Format memory. If asked format for Map.

    If that works you should be able to select a map and load it from MyDrive Connect.
