Great review and thanks for taking the time to post it. Have you experimented with the turn by turn voice yet? I have a 3 year old Nuvi and a loud Jeep and I can barely hear my Nuvi's speaker. I heard the latest models can play the voice through the car's radio via an FM signal but it sounds like this feature was left out of the Montana. I'd really like to hear more about the Montana's speaker if you've used it.
