I don’t know if it is classified as an emulator but http://www.gpsunitsandaccessories does carry a software package with an antenna to make your PC into a GPS navigator. I checked into this while looking into a new Nuvi 265WT that I just bought from them. Check it out at http://www.gpsunitsandaccessories.com/product/32028 Hope it helps.
