I was updating my maps and during the download the system told me that I did not have enough space on my device. This has never happened before. Does anyone have any suggestions on which files/folders I can delete. I have 4.64MB of 1.91GB remaining. I have not loaded anything other than what came with the device. I have US_Canada_Mexico maps on the device. Unfortunately, the device does not allow me to use an SD card. Does anyone have any suggestions on which files/folders I can delete to free disk space?
