Finally!
Issue resolved. The problem seems to be topo map files created by "maps4gps".
I tried installing maps for other states by this same creator and none of them would show up in BC.
I then installed a different WA topo map option by another creator and it worked the 1st try!
Thanks for everyone's help! Now I can go geocaching with my new Oregon 450t!
