Do GPS units usually come with software?

Question

I'm doing a lot of research on GPS units, but none of their websites seem to say whether or not they come with route planning software, update software, etc. What has your experience been?

I need a unit that will plan and optimize (not just sort) a route with up to 80 waypoints.

Answer 1

while all PNVs (personal navigation devices) come with software for routing etc, i am not aware of any that will optimize your route.  it would be a nice piece of functionality but from what i've seen you have to define the order yourself.

best of luck.
