I have an Oregon 600. I had a 32GB micro sd memory card in it to store my routes. I have just purchased a full uk OS map for it, but this is only on a 4GB micro sd card and is not big enough to store my routes on as this as well. I have tried to copy the map to a larger micro sd card but it is not recognise. How do I resolve this.
Also Basecamp will not copy a backup from this card. Is this the same security problem?
