Quote from: davidklein on October 14, 2009, 06:46:32 PM1. When hiking I want to use the topo map; when biking the CN. Do you disable Topo map when biking, and vice versa when hiking?
2. How do you know if the sd card is being used? I looked at the Garmin drive in Windws Exploere properties and only saw 900 meg, which I'm guessing is the internal built in memory. Also - how do I direct maps to the sd card?
1) Yes, that will work. In practice one will always cover the other (probably CityNav covering topo) so you will only have to disable/enable the top one (probably CityNav) when you want to use the other one.
2) When you connect in mass storage mode and you have a sd card installed you should see two drives within Windows Explorer. The first one should be labeled Garmin (or Garmin Dakota?). The second may not have label and will just say "Removable Disk". Once you find it you can right-click, select properties and give it a better label. When you are in Mapsource downloading maps, on the final dialog hit the drop down box and select the sd card.
I'm not certain on which one (internal vs external) the units use by default - I've been mostly moving things around by hand.
