Speed warning

 

this is my requirement

i have a garmin c320 .. i want to use it as a speed warning device either in one of the following two ways

#1 Predefine 3 threshold speed limits in the system say 30/ 40/50

any time i cross the threshold the deviec should give an audible beep informing that the speed has gone over a certain threshold.

#2 since the device already has the speed limit of roads whenever my speed is say 10 miles over the road speed limit, give an audible warning

is it possibe..

thank you ..

Speed Warning

I do not believe that you can do #1 or #2.
What you can do is create a POI file with specific locations and a speed alert. Then, when you approach the location, if your speed is over your set threshold, an alarm will go off. There are POI's for speed traps and that is how they work. The whole file can be set with a single speed or individual entries can have different speeds.
