Pros:Inexpensive, easy to install and operate. Can save me from many delays.
Cons:Reports only what information it is provided. Not it's fault.
The Bottom Line: All in all a good performaer. Based on information provided by the traffic system, it works well. It depends on the traffic sensor infrastructure in each area. Results may vary.

I had my TomTom device for a while, and was getting more concerned with traffic jams and incidents, so I decided to buy this sensor. Note: The traffic sensor reports freeway information only!
Installation and setup:
The sensor replaces the vehicle power cord. As such, one end plugs into a typical vehicle power/cigarette lighter socket. The other end plugs into the USB jack on the bottom of the unit.
Once powered up, the GPS will indicate the traffic sensor is plugged in, and a vertical information bar will appear on the right side of the GPS unit. The unit will begin scanning for a radio frequency that carries traffic information. By accessing your preferences on your GPS unit, you can also tune directly to a radio channel you know has the RDS/TMC data. Once the unit has tuned and acquired a signal, a solid green indicator will display at the top of the traffic info bar.
First, enter and accept your destination. After that, you will see the traffic information bar change. At the bottom, you will see an arrow symbol. This is you at your current position. At the top there is a "checkered flag" icon, which indicates your destination. It, on your route, there is a traffic incident, there will be an icon somewhere in the line between the two points. This icon will also be labeled indicating the distance to the incident. Your gps display will tell you the delay time, and suggest an alternate route, if there is one that will get you to your destination faster.
You also, can tap the traffic display and get a menu. The items it contains diffter with models of gps receiver; but they typically can give you a list of traffic incidents in your area, traffic on your route, and other items.
This sensor only reports traffic conditions on interstates, and other major freeways in an area. Also, only in areas with the RDS/TMC traffic data broadcasts, can you get information.
The completeness, reaction time and coverage ares of traffic information is dependent on how each area's Intelligent Transportation Systems are configured.
What one user in one area may experience can differ from a user in another.
I, personally, have found the information generally quite accurate. I live in Columbus, Ohio, and the ITS infrastructure is fairly complete. Additionally, there are several RDS/TMC stations in place. I have been redirected a few times, and have been pleased with the information provided. On a recent trip, we have received traffic data, although, no incidents were reported or encountered.
