I am almost certain of the answer already but thought I'd try any way.. Does anyone know of a way to easily use garmin based software for the GPS V (or another mapping software that is compatible) on the mac platform?? I know from the Garmin site they don't have the software yet and the do offer a way to connect the two by building your own cable!!! Just curious?? Maybe I need to switch gps brand? I won't give up my mac!!
