This was a second N810 .I returned the first because I thought that had a defective GPS.
As I stated above it did lock in quickly twice the previous night.
It was placed in same exact window next morning and did not show anything for five minutes. This is not a reliable product for $479.00.
My Garmin Nuvi 350 will lock in within 1 minute no matter where I turn it on.

GPS in this unit is too quirky and not worth having it built into this generation.
I bought N810 for many reasons other than GPS but I feel if you are paying for a feature it should work.
There are other devices available with bigger screen, more memory and faster processor for less money for internet use.

Nokia should have left GPS out and priced lower to compete with linux devices that are now coming out.
