I do not think so. Maps are released by a few map makers and licensed for use. A GPS maker reformats the map info into a proprietary format that is recognizable only by its GPS units. And No you cannot use maps from one GPS maker on a model from another GPS maker. However nothing prevents you from trying it, but before you do so, make sure that you back up all the content of the GPS unit.
