Reading the [Only registered and activated users can see links. ] is always the best place to start, particularly maybe [Only registered and activated users can see links. ]. Giving more info on how you're trying to install them would be good to. Read the tuts and if you still are stuck, post again. For instance, are you using a patched version of BaseCamp/MapInstall to load the images to your 200. If the maps are unlocked only for another unit they won't be available otherwise.
