alert of way points

[Euan Uzami]

is there any way of causing my eTrex vista to do an alert - e.g. beep, when i get to a certain point?
I use MapSource with city navigator, and have an etrex vista hcx.

i.e. I want it to be able to tell me "information control soon!" or "cafe HERE!" (not just if I happen to be looking at it) so i don't miss it!

ah ok cheers, i'd just discovered that as i was playing with it.
i don't suppose you know what each of the following signify:
 "UPcoming speed alert"
* "Proximity Alarm Beep"
* "Leaving proximity beep"
* "Approaching proximity beep"
?
i.e. what causes each one to fire?
