Our day to AK was shared with a GPS unit they where testing. Not the best in my opinion but if it works out I'm sure there will be many who will opt to have it around their neck as I did for the day. There were a few people who had them and were having a good time with them, They called them FUN FINDERS. I would of liked to taken the SD card and put it in my Garmin Nuvi to see if it worked.
