Santa brought me a new 60 CSX - what a guy. I am planning on a boy scout trip to Isle Royale this summer (can't wait to log the earth cache there). My question is, I want the topo maps for the unit. I have the choice of a plug in chip, or the dvd for my computer. I also want to be able to log our entire trip as a trail and store it on a memory card (I have alot of wants, I know). 50 miles over 8 days of trails - will that fit in the unit memory, or do I need a storage card? My initial thought is to get the DVD of the national parks and just download the topo info of Isle royal to the memory chip, and use the rest for trail storage?
Any suggestions? also, whats the largest chip the unit will take?
