By Diane Sanders “Obi Wan Nuvi”

After much research I decided on the Nuvi 255 due mostly to the fact that it is the least expensive model with TTS (Text to speech) in other words it speaks street names so that you can keep your eyes on the raod ahead.

This unit also has the ability to get traffic updates via a separate cable (GTM-10 or GTM-12 Traffic Receiver) that can be purchased through Amazon.com. I have not purchased this extra item, so I cannot comment on how this works.
