Does anyone know how to upload information from more than one Mapsource program onto my GPS device. I have the yellow Meridian, I also do both a hiking and city use with my GPS now. It seems that you can use either Mapsend Streets and Destinations or Mapsend TOPO but not both to d/l regions. When I import a file I created in S/D into Topo it only picks up the POI that Topo has. Thank you,
