I've been meaning to share my impressions of using Navigon over the last 6-8 weeks in and around Toronto. I'm not much of a writer and will aim to keep this brief. I've been using Navigon's Traffic addon from day one, which is supposed to consider traffic information when calculating routes. I regularly make a 150km (~93-mile) trip to the Niagara region, which is a fairly linear and predictable drive, but also use Navigon for driving around Toronto (I'm fairly new here). Overall, I've been extremely disappointed with Navigon. More often than not, Navigon actually seems to make my drives LONGER than they would be if I just stuck to my usual routes. I can only make that judgement on routes that I'm familiar with, which is the bulk of my GPS usage. A big part of the allure of Navigon for me was the traffic updates, in the hopes that they would direct me around congestion. A frequent problem with Navigon is that it will recalculate the route based on traffic information without updating you if your current instruction changes. For example, I have several times been prepared to turn when the software adjusts for traffic, only to discover that my instructions have changed and I'm supposed to go straight instead. The software makes no announcement to correct the current instruction, so you need to keep an eye on it when it recalculates the route. Navigon seems to have no concept of traffic trends or history. It could just be my experience, but it seems to only consider traffic information at any given moment in time, which is almost completely useless. The other night, my estimated driving time steadily increased by about 50 minutes in a 15-20 minute period. On one occasion, on the 401 in Toronto, the estimated time was about an hour later than it turned out to be. This is especially shocking when considering how much traffic information Navigon must have access to for a city such as Toronto... I just don't get it. If it's that bad and unusable in Toronto, I can't imagine it being worth the hassle or money anywhere else. I have not used any other GPS software to date, and am somewhat reluctant to roll the dice and spend more money after this experience. Here's hoping Navigon gets their act together and comes up with a more effective method of estimating traffic and adjusting routes accordingly.
