Hi, when I connect the Zumo to the iMac, it appears in the top left, and the data held on it appears below this in a separate window. If I remove an item by deleting it, the Zumo Icon under my devices Top Left, spins around, as if it is deleting it, but when I disconnect the unit, they are still there on the Zumo? Can anybody help, it's doing my head in. Thanks - Alan
What data are you trying to delete? Was it sent there by Basecamp or any other program? If it was there will be a .gpx file, or files, in the GPX directory, you'll need to delete that first otherwise every time you switch the zumo on it will reload the data from that .gpx file.
