with my nuvi55 when i try to enter 3 addresses one at a time (im a real estate appraiser) it does NOT optimize those addresses for fastest way to get to all 3 three. i even tried trip planner and still doesnt put them in geographic order from where im starting. it just puts them in the order they are input. also i want the option to SPEAK my destination/address if i dont want to type. do any new units do these? thanks
