Hi - I have recently updated the maps on my NUVI with no problems. Have done this before, so was really a non-event. I was poking around today on my Laptop, and discovered that I have 3 versions of backups for my Garmin, each taking up something like 2.4GB of space. I'[m not exactly short on space, but it seems to me that 1 would be enough, considering how well the unit is working. Any problem with deleting the older backups? Thanks in advance.
