new to the gps world here. i am using an older mac book MAC OS X Version 10.6.8 and im assuming an older version of base camp. i just bought a new garmin oregon 600 and im trying to just do a simple download from the filedepot and upload to base camp. the files are coming into my downloads but when i go to import out of base camp the files arent coming up under the "readable file" option. if i click "all files" then i can now click on the downloaded topo but then it wont import into base camp. these files are coming in as newenglandtopo.tar( and or ending in .gmapi .tgz.download ) Files ending in .gpx upload will upload with no issue though. any help would be great. thank you
