My TomTom One XL can be set to give a warning if you go over a given speed. It can be adjusted. I had a Garmin Nuvi and it couldn't. A coworker has one called a Nextar and you can set that to give a speed warning too.
The automatic one where it turns the number red only works on certain roads, mostly interstates.
That sounds like exactly what I'm looking for Blk04. There is about 4 different XL's on the Tomtom.com. Which one is it? Is that what they refer to as saftey alert.
Thanks
