Thread: Nuvi 1300 issues

When you connect it to GarminExpress, it should correctly determine if an intended IMG file will fit directly on the device and advise you accordingly. It normally won't prompt you to load a map that won't fit in the available space. I suspect that the lower US map did in fact fit but had corrupt data in it. That can happen and in fact did happen quite often in earlier versions of GE, but later versions are far more reliable. Any disturbance during the loading will certainly cause problems of course and even with modern internet speeds a large file like NA can take quite a while to transfer, increasing the chance of a faulty file.
