Neither Map Updater or Garmin Express will 'find' my Nuvi
it used to be as easy as opening the program and plugging in my Nuvi 1450LMT. now only my computer finds the nuvi but i have no idea how to update the maps. i looked in the sticky threads about to manually update maps but didn't find anything. how can i get the programs to find my Nuvi?
