My whole point to this thread was to advice in my opinion that GPS is weak in this device. If you are looking for True GPS buy a good stand alone unit.
My Garmin Nuvi 350 will find location indoors or outdoors at any location within 60-90 seconds.
I can say with certainty N810 can not do this.
I wanted a second GPS alternative to Nuvi in case I decided to give it to Wife or daughter.
N810 is not alternative at this point.
Maybe future unit will be along with better mapping software.
You must admit that software could use improvement.
