I’m in the same boat as Campbell when I used Navizon for a couple days in Texas it was about 8 miles off. Until the accuracy and technology imrpoves I’ll hold on to my Garmin Nuvi GPS.

I used navizon for three days in Cincinnati, OH. It only found my position once, and though it was in the right part of town, it was about 5 miles off. Not useful for navigation.

Seems the technology is dependent on people across the country/world registering wifi locations (not sure how cell towers work but I assume it’s similar). You’re going to need multiple wifi and/or cell towers near you to triangulate. In my opinion, this will never come close to GPS accuracy. It will probably get better, but not because of new versions of the software as much as growth of the database, increase in number of cell towers and wifi locations, and probably never in rural areas.

This is from the Navizon website…

Navizon is a software-only wireless positioning system that triangulates signals broadcasted from Wi-Fi access points and Cellular towers to help the users find their way in most major metropolitan areas worldwide.

The Navizon network is based on a collaborative database. Members with a GPS device can use Navizon to map the Wi-Fi and cellular landscape in their neighborhoods. Once they synchronize their data, it is made available to all the other users of the network. This way, users who don’t have a GPS device can benefit from a positioning system.

I agree with Brian, I live in the Netherlands, my position was off by about 10 kilometers. Not very accurate, you must admit…
I thought the program looked up my ip and got the position through this way… Why not incorporate a bluetooth connection into this and have this program work with bluetooth gps? I suggest downloading your route at home with wifi, then save it in cache and then start driving, using bluetooth gps. Until then I will also hang on to my TomTom.

David, don’t just compare your info but others as well. My navizon I installed said the same thing and was off horribly. I put a complete address (which is just across the street) and was told my trip would take 3 days. its still in its early stage and hopefully it will improve, but until then, im holding onto my tomtom.

Dave, it is difficult to provide a thorough review of a program which didn’t work properly, and continues to not work properly. Over the past two weeks I’ve traveled 1,200 miles testing other equipment and experimenting with Navizon along the way. So far I haven’t seen any improvements in my results. I tried to acquire my location 19 times, with each area about fifty miles or so away from other areas I tested to try to get a fair sample. In 12 of those cases I had a wifi connection in addition to a cell signal. Only one location was found by Navizon, and again the location where it mapped me was over 100 miles away from my actual location.

I’m glad it is working well for you, but it looks like unless you are in a big city the results will be less than stellar. Navizon looks like a really neat program and I’ll continue to follow its progress, but it is hard to give it the thorough review you are looking for when I can’t get it to work.

I find your review a bit superficial. I am using Navizon since it was launched and it has kept identifying my accurate location ever since (OK, I am in the Bay Area but still).
As for saying that it puts you 2,228 miles, this is totally dishonest and you know it: while the pin indicates the location that Navizon finds, the addresses associated with the routes are coming from Google Maps not Navizon.
So with all due respect, I think that your review lacks a little bit of thoroughness.

Oh and I forgot to mention: I am not affiliated with Navizon in any way. I am just using this product on a regular basis and really love it.

Valuable reality check… 2nd prior comment to consider this initial test as a baseline, perhaps re-test in 3, 6, 12 months. Thanks.

The dates of publication (typically close to the date of test) are shown just above the comment area. I believe the version of Navizon was 1.0.1.

It would help if you provide the date of the review/test, and software version if available. Then after a while one can compare to see if the unit/software has been updated for features or fixes. Your forum is great with lots of information.
