The Motorola V360 isn't on the list of compatible iSync devices (while your Nokia 3650 is):

That's the reason iSync doesn't show the v360 as a compatible device, but does allow you to sync the Nokia 3650.
You'll need to hack some of the drivers to get the v360 to function with iSync -- it's not all that hard:
