I have a Nuvi 260W that's about 8 years old that I haven't used for awhile but I need it for a job. I read rural water meters and I need to mark each meters coordinates and add it to my Favorites list. When I connect it via usb to my computer if shows I have 111 mb's free out of 1.21 GB's so apparently it doesn't have much internal memory left. I'm assuming I won't have enough free memory to add about 150 Favorites correct? I have an SD card installed so will the 260 start adding data to it once it's internal memory runs out? If not is there anything I can do?
