Designed exclusively for the American version of certain products, it receives digital information (where available) on traffic and road construction tie-ups that your compatible Garmin unit uses to offer an alternate route. TMC data, available in a fast-growing number of cities throughout North America and Europe, gives prompt, accurate notification of accidents, road construction, police, or emergency action, etc. so you can visually monitor traffic flow and, if necessary, avoid traffic tie-ups.2.Receive Real-time Traffic Data -- In most areas, depending on the service provider, TMC traffic broadcasts are continuous theres no waiting for scheduled traffic news updates or random alerts. With the GTM 20, you see traffic developments in real-time, as they happen, so you can make the right decision sooner. The system alerts you when a traffic problem is on your route and proposes an alternate route to avoid the incident. Because traffic broadcasts are received via a silent FM data channel, you can still listen to music or news programming on your car radio without interference from incoming FM traffic data transmissions.The GTM 20 is a portable, all-in-one antenna, traffic receiver, and 12-volt cigarette adapter that does not require professional installation. | | | Features: | |

 Unacceptable Build Quality like typical China Made.Oct 19, 2009
I just can't believe Garmin has not done anything with its supplier with lousy build quality. Chinese made is cheap but quality is usually lousy. Not sure but I got to believe this is made in China.
 Fell ApartSep 23, 2009
After less than a year of use, it fell apart and part was stuck in my cigarette lighter/ plug.
 GDB 50 and lifetime serviceJul 23, 2009
Does the GDB 50 come with lifetime service? First you pay for the cable and 1 year service then after a year another $100 for the MSN lifetime service.
Unreliable - or at least it wasMay 01, 2009
I've had this for a couple of years, it still powers on OK, however it won't stay locked on to the signal. I live in the San Francisco Bay area, so radio reception should be no issue, yet each time I come back to the car the thing has lost lock again and I have to power it down so it can restart. It will run for a few minutes, or half an hour, before it drops off again. So much for realtime traffic information.
The price is ludicrous, this thing should be thirty bucks at the very most. Knowing what I don now I'd think more than twice before I'd buy anything that used this receiver again.
Update
After several years of using this thing it looks like the software and systems guys have sorted their act out. This seems to have become more reliable. There was a terrible patch where the thing pretty much stopped working, about the same time as there was some discussion of ClearChannel having messed up the traffic reporting, and then it came good. No idea what happened. There was a software update which didn't mention anything that should have affected this. Anyway, it works well enough, just pay the extra five bucks for the lifetime subscription that doesn't include adverts.
The traffic information delivered still isn't fantastic though.
