I have 180 pixels or so to see what's ahead of me on Crossover. So if you have two rows of info fields on, only about 30 pixel tall area of the screen is available to see where you are going. Also, unlike Oregon or Crossover, information fields are not transparent AND your position is in the middle of the remaining screen, not at the bottom. PN-40 just offers to turn off GPS to save the power.ĥ. Neither my Garmin Nuvi 260 nor my Magellan Crossover does well in Manhattan - they occasionally lose connection or show me 100 yards away from the real position - but they are still usable there. In dense skyscraper areas PN-40 was not capable maintaining lock. I cannot be checking the unit every 5 minutes to see if it needs reboot to restore the connection.Ĥ. Without this geotagging becomes a nightmare. If it loses lock due to some reason, I expect it to lock in again once signal becomes available. I expect my GPS unit to reliably record the track while sitting in my backpack. Turning the device of and back on resulted in a strong 3D lock within couple seconds. I chose not to but waiting more did not help. I was standing in an open area and just watched the dance of red bars until I finally was prompted to disable the GPS. That happened only three times in two weeks of active testing. Without any appearent reason PN-40 looses satellite lock and is not able to lock again unless I turn it off and on. This is the single most important reason why I am about to return the device back to the store.

Apparently firmware upgrade only improved accuracy estimate but not the true accuracy.ģ. Once upgraded to 2.5, I saw much better accuracy estimates on the device - 10, 8, 6 feet - but once I repeated the test I did not observe any real accuracy improvement. Delta of imagery across providers was never more than 1-2 feet delta with my waypoint was 20-15 feet, depending on location. I verified actual accuracy by recording multiple waypoints on clearly visible places like the center of paved trail crossing or specific place in a parking lot and measuring its distance to the place as seen on Google Earth, Microsoft Virtual Earth and Yahoo Maps. With firmware 2.0 estimated accuracy never got better than 20 feet. I was not able to do that again anywhere including the top of the hill with 20 miles clear view in all directions.Ģ. With 2.5 I was able to get a lock once after spending 30 minutes in the middle of the stadium.

With firmware 2.0 the best I could get was one blue bar for a few seconds. PN-40 in practice is not a WAAS-enabled GPS.

I am in software industry for many years and I am used to all kinds of user interfaces and have no issues with learning yet another one.ġ. That includes contributing hundreds of geotagged photos to Google Earth via Panoramio, building recorded track database of less known trails, taking off-trail hikes planned using Google Earth imagery, geocaching and many other. Nevertheless, if you know the workaround or solution, I would really appreciate your reply.įirst about myself: I use GPS technology for a variety of activities for a while. I spent significant amount of time reading forums and vast majority of issues I listed here are well discussed but with no solutions. I hope listing the issues will help people to make more informed buying decision. There are lots of reviews stressing on positive sides of PN-40, so I will skip on that. I spent two weeks actively using my new PN-40 and I would like to share my observations.
