I have a TomTom XL-340 GPS and this unit is not compatable with it.
The connector for this unit is a mini-jack similar to that of a pair of headphones but smaller. My GPS needs a mini-USB connector.
Would be nice to have a list of compatable GPS units or an indication of what type of connection this unit uses.
Only reason it gets 1 star is because I can’t rate it 0.

Works great and very cheap. I sit it across the dash and it works fine.

Received reception at 97. 5 in NY. Shows some traffic, but often none is shown while I am siting in it. no problems with reception.

FYI, the receiver does not look like the picture, but the important this is that it is a pin-type connection (some require a USB connection – if so, this is not for you!)
All I had to do was plug it in to get traffic info. I live in Birmingham, AL. So far, I haven’t used it during some of the worst traffic. I have noticed it won’t report “congestion” (your typical 5 o’clock slowness) but only atypical delays, so just be aware of that. Otherwise its fine.
UPDATE:
I went to Atlanta today where they have much worse traffic. On the way home, cars started to slow and I could see impending bumper to bumper traffic ahead. At that moment, the GPS alerted me there was traffic ahead and I had to option to chose a faster route. I got off at the next exit as advised. On the overhead bridge, I could see the others in traffic as I continued to make my way along a clear route. I’m convinced.
As far as picking up a signal, I only lost a signal once during the most remote part of I-20 for about 15 mins, otherwise it was “green” the entire time.
