I am doing a TAT trip this summer. I will be using Sam's GPS tracks. Would I be wise to load the Maps (CNNA, Topo) and all the tracks on the SDCard and making backup of the card? Or would I be safe putting maybe the CNNA maps on the Garmin memory (CNNA and Topo will not fit on the internal memory together)
