I am mainly interested in the thompson, Caribou area i guess central B.C. two of my friends just purchased Garmins and it looked to us like the magellan topo was more detailed whith back roads and small lake names. I think one of my friends will be returning his map 60 csx for an eXplorist, Im quite happy with the topo for my 500. We were just curious to see if any one else had any thoughts on this, thanks.
