Most of (all) Garmin nuvi devices do not accept second map file on SD card, so only two solutions:

1. Transfer both maps in one file from PC (MapSource/MapInstall) or Mac (RoadTrip/MapInlstall), or
2. Join maps in one file with Gmaptool ([Only registered and activated users can see links. ]) on PC system and copy to SD card
