What is the proximity alarm in 5.x firmware?
A proximity alarm sounds when you are approaching the next point in the active route or the current goto. The ‘distance’ value has a fudge factor that seems to involve your velocity so that the alarm fires a few seconds from arrival. This is used to deliver the turn-by-turn pop ups for DirecRoute. See also: arrival alarm. It’s worth noting that Thales’ use of the term “proximity alarm” for this feature is inconsistent with industry norms and bears little resemblance to what Garmin and others call proximity alarms.
