Traffic Monitors

Does anyone know of a Garmin GPS that has a traffic monitor that is as good as the Iphone3GS's built in traffic monitor? The Microsoft traffic shows major highways and expressways but has virtually no street level info and it is obviously not used in routing at street level. The Iphone, if your navigator can utilize it while you drive in city traffic in Chicago, accurately shows traffic levels on many major streets and is much better for quick navigation. On one recent day, my Garmin gave me a 1 hour plus trip for a 12 mile drive (which was reasonable for the time of day), yet I was able to complete the trip in about 25 minutes using the Iphone traffic. If Iphone can do it, I am sure Garmin should be able to get the same info.
3 sources
There are 3 sources for traffic and they can be classified as mostly right, occasionally right and never right. Just read through the various threads here.
But kidding aside, the main providers are MSN, NavTeq, and Clear Channel. All use some of the same raw data from sensors installed by state highway departments or local public works agencies. Other sources are cell phone providers and monitored traffic cameras. Some networks are more robust than others and will cover more streets but none of them cover all the streets and highways in any given area

Every area is different, but for the New York City metropolitan area, I am for Clear Channel.

Dear Dobs,
Are those the horrible people who banned the Dixie Chicks from their air?

You are probably right - they own most radio stations in the US, but that is where they get the good traffic content!
