What's "Speed Alert 2mph" on my Garmin


I just recently got a Garmin C550 which has the FM traffic. I'm not sure if it's from the FM traffic alert by when I come to some intersections around my area (Metro West Boston), the top banner on my GPS turns red with the words "Speed Alert 2mph" and a loud alert tone. Is this from the FM or from one of the POI that I may have loaded. Is there some signal in the sreet that causes this?

I'm not sure either

I'm not sure either. I have a Nuvi 670 that giver’s me speed alerts of 12 MPH when I am in or near some parking lots like Home Depot. I had just assumed they were in with the red-light camera poi's that I loaded but maybe not.

nüvi 660 & 670 - Hello I'm a Mac :))

poi file names?

Do you have custom poi files which have numbers as part of the file names? e.g. homedepot1.csv? That number may be loaded with the pois as speed alerts. I might be wrong and some more experienced persons may be able to speak to this.
