I tried to update my old Garmin C320 to 2010 map but failed. The MapInstall asked me to active map *online* so basically there is no where to input unlock key. Some IDs suggested to install 2009 map instead. ps: Garmin C320 use SD card to store map, I also tried saving 2010 map image and unlock code file on SD, no luck.

I tried this way but it did not work. Garmin C320 map is totally based on SD card (no internal hard drive). The instructions in previous articles for C330 might not be applicable.
