Hi -- I know that there are workarounds to copy a Garmin Mobile XT card to a larger SD card utilizing UNL files, but there was a question and answer provided in their knowledge base that triggered another thought. When asked about copying to a larger card, Garmin responds: No, the mapping on the pre-programmed Garmin Mobile XT card is locked to the internal serial number of that specific card. If you attempt to copy the mapping onto a larger card, you will be asked to enter an activation code which you will not have. Is there a utility that will read/write an SD's card's internal serial number? Since I own/purchased this card, I feel it's within my rights to copy it to a larger card. If I can read the internal serial number of the Garmin card, I would want to copy that internal serial number to my larger card (I have a SanDisk 8G microSD).
