Made one by one. Manually positioned POI's and alarm circles. Works flawlessly on Nuvi 2xx and 1xxx. The same POI position can be used for entering speed limit zone and exiting it in the opposite direction. This allows for direction-dependent sound and on-screen message for the same POI. Two configuration xml's are required though, one for each direction. At least, that's how I got it working. Built-in sounds are used for alarms as custom wav or mp3 often hangs Nuvi if alarm sound coincides with turn annunciation. Couldn't get it working on SP at all. Tried alarm circles and bearing list separately and in combination - no luck, SP sounds off alarms in either direction.
