I explained what previous owner delete files obviously. It is usually dealing to clear memory for free space. Otherwise the updater give you suggestion to load new version of text files for menu. prx - speed alert file and trf - traffic announce file.

About keyboard you are wrong! The first way, you must put nuvi12xx_13xx_14xxKeyboards_320.rgn to Updater or Webupdater icons and this program will do all for you. The second way is for developer, rename nuvi12xx_13xx_14xxKeyboards_320.rgn to D162200.zip, delete Garmin signature and only then copy to Nuvi. I had see you are never read forum threads at whole before do any things. Do you love a great deal of problem?
