No it's not. I think better comparison than your standard Tomtom or Garmin navigator of N810 navigation is Windows Mobile navigation software that depending on your device may come with software or you have to separately purchase. For example: http://navngo.com/pages/global/eng/igo_8_description

I used N810 with Wayfinder in April on my road trip around Lyon area France. I was perfectly satisfied with the experience. Sure there were a few roundabouts that were not in the map data and a couple of times it thought we were on a parallel road but no major issues. I suppose I am more tolerant to map data issues than some people in other threads. I want my navigator to give me a basic idea where I am and can tolerate it not providing perfect directions from A to B. Usually I keep my eyes open when driving and can adapt to differences between map data and what I see ahead of me.

The GPS fix times were better than I anticipated. First thing I did before loading up the car was to start Maps and let it start getting a fix. Usually this happened in <1min. So by the time we were ready to depart the fix was there.

I am not denying that the navigation software and GPS fix times need improvements but I was perfectly satisfied with the experience . That one device can provide navigation and everything else N810 has, is a huge deal for me.
