Summary: I was disappointed to find out that if you are wearing sunglasses, you can't see the screen. While the NAV300 works great, I was also disappointed with the voice commands. They are hard to understand and don't have a TX drawl. I think a cheaper model would be a better buy. I like the Bluetooth, but the MP3, video, pictures, etc. are wasted features. The speed alert is very helpful on major highways and POIs are a great addition to plain roadway signs.
