XM Radio is doing everything it can to make your life easier, and finding you a parking spot is topping the list. Using "Dynamic Parking Information" developed with Nu-Metrics and InfoGation, the system searches nearby parking garages for the closest available spot and displays it via your car's navigation system. It'll use color coding to indicate how much parking is still available in a particular building. This is a huge benefit for anyone driving in the city and trying to find desirable parking. Sheer genius. XM is only testing this right now, but it should become available in the near future.
