multiple tourguides how do they interact

 

I have a nuvi 350 and installed two TourGuide POI's - McDonalds.csv with a distance of 3 miles and NP _towers.csv with a distance parameter of 15 miles. When they overlap, I only get the prompt for McDonalds which is the nearer one. What is happening to the alerts for NPR?
If they are "active" how do I "see" them.

With Appreciation
