If you were thinking about buying a shiny new GPS unit for Christmas, save your money and get the service for free on your phone.

Highlights of the service include:

• Search in plain English (watch video). No need to know the address. You can type a business name or even a kind of a business, just like you would on Google.
• Search by voice (watch video). Speak your destination instead of typing (English only): “Navigate to the de Young Museum in San Francisco”.
• Traffic view (watch video). An on-screen indicator glows green, yellow, or red based on the current traffic conditions along your route. A single touch toggles a traffic view which shows the traffic ahead of you.
• Search along route (watch video). Search for any kind of business along your route, or turn on popular layers such as gas stations, restaurants, or parking.
• Satellite view (watch video). View your route overlaid on 3D satellite views with Google’s high-resolution aerial imagery.
• Street View (watch video). Visualize turns overlaid on Google’s Street View imagery. Navigation automatically switches to Street View as you approach your destination.
• Car dock mode (watch video). For certain devices, placing your phone in a car dock activates a special mode that makes it easy to use your device at arm’s length.

I really hope G1 owners get Android 2.0 now.
