Over-the-speedlimit alert

 

Is it possible to create a POI file to alert me if I'm going over the speed limit? I have a nuvi 755t, which displays the speed limit data.. this would be a very useful piece of functionality, especially if one could configure the amount over the limit before a notification is displayed/sounded.

I wasn't able to find this in the forums; apologies if this has already been discussed.

Cheers!
