Seems to work ok ... but
Used the product to drive to Fla via Rt. 95 in December. The yellow warning showed traffic congestion ahead in NJ & DC but when we got to the area in question, no congestion.

Simplified my Life
I have a Garmin 765T that already came with a GTM 20 with Lifetime Traffic. The problem is that I ride a motorcycle and this power/antenna cable runs from a handle bar mount, under the gas tank, to a socket under the seat.

Neither rugged or accurate
I love my Garmin Nuvi and I hate this GTM device.
When I bought this I used it religiously in all types of traffic conditions, but strangely enough the information it gave me was inaccurate or worse, often causing me to make very bad decisions like avoiding a highway because it warned me of 45 minute delays when friends of mine took that same route at the same time and had no problems, or when it would tell me to avoid a jam by taking a side street in a bad neighborhood where I ended up motionless for 25 minutes before being able to proceed the two blocks needed.

not the one shown in the picture
It works, but it's not the model shown in the picture. It's a different one that has a much thicker cord and no charge indicator lights.

Traffic Alert Works
I've used the traffic alert system for a couple of months and it has provided good information for both rush hour/accident traffic slowdowns and weather affected traffic slowdowns.
