 Cheaply Made Adapter August 3, 2010
Joseph Waitman
I see from the reviews that my adapter isn't the only one that broke while trying to remove it from the plug in my car. My cheap phone charger is made to last a lot longer than Garmin's cheap charger. I can't use my Garmin now, not sure I want to buy another GTM 20 or try something else.
 Unacceptable Build Quality like typical China Made. October 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.

After less than a year of use, it fell apart and part was stuck in my cigarette lighter/ plug.
 GDB 50 and lifetime service July 23, 2009
Michael Manieri (West Chester PA)
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 was May 1, 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.
