This may have been posted here before but it's news to me.
Google and Mapquest both have the ability to send an exact location to a GPS unit.
I use an Edge 705 on my bike and just got a Nuvi 205 for my car. Also living in Japan I can have my wife google map up someplace I'm looking for and then transfer that point to the GPS unit as a favorite.
I could try to explain it but this web link does it better.
