I purchased the Oregon 450t which had the Topo 100k base map already installed. I also own an older version of Mapsource, Metroguide. When I upload a route from base camp it tells me there are no routable maps available. I tried with the topo map enabled and with the metroguide map which are supposedly routable,. Can anyone tell me what the problem could be and if I decide to purchase city navigator will I be able to get the oregon to route maps with the uploaded mapset from this software?
