The Dash Express is the first internet-connected GPS receiver. The main benefit to the Dash is the real-time traffic updates that use the Dash Driver Network to show you traffic in your local area. The Dash Express connects to the internet via cellular or WiFi radios, depending on proximity. The GPS works without internet connection if there is none available. It's important to note that the internet connection associated with your Dash requires a monthly subscription fee ranging from $9.99/month to $12.99/month, depending on your commitment (2 year to monthly).
