Well, downloading has given me problems. I have a Garmin nuvi 500 and a PC with IE6. When I click the download GSP button from the Geocaching website, I get a Garmin window that asks if I can't get it to run and suggests I install the latest pulgin. When I download the plugin it happens again and again and again. Any ideas as to what I am doing wrong???

I cannot upgrade to IE7 because my scanner will not work! Is it possible to get up loads to my Garmin using IE6? Any ideas?
