[Desire HD Themes and Apps] betelgeuse74:
Thank your for your guide!

I am currently testing CoPilot Live 8.2, Navigon 3.5.3 and Sygic 2.0 (don't have the latest version unfortunately). Here are my initial views:

CoPilot Live 8

My impression of CoPilot is not that good. The user interface is way too advanced and complicated. Navigating through the menus takes a long time to learn (compared to the others at least), and is not very intuitive. There are several ways to reach the same settings, and it makes the configuration very complex. It has very annoying voice guidance in Norwegian. The voice starts almost every sentence with "Just ahead". Navigation interface is ok, but the information bar icons in landscape mode are too small. The deal breaker for me however is that, out of the three, it does the worst job in guiding you. I was unable to configure CoPilot to choose the optimal route from home to work. No matter which settings I tried I was always directed through downtown instead of using the ringways (No motorways allowed?). It also seems that the maps are a little imprecise. When driving home I arrived at my destination 500 meteres before I was home. (Navigon in this test was spot on, giving me notice as I'm driving into the garage.) On the plus side it has the best POI functionality of all apps I have tested!

Navigon

Navigon may lack some features, but it works, and even though the interface is simple, it is my preferred solution as of today. I like that it gives me a choice of which route to take before starting. Navigation seems reliable and instructions are given in good time so you don't miss your exit. Navigon is well integrated with contacts, so choosing a contact and navigation to him/her is easy. POI functionality is OK, but integration in navigation mode is not the best. It does however have good search functionality, which includes Google Search, and it gets positive remarks for reality scanner. Navigation interface is a little boring and there is no full screen view (status bars on top and bottom make the navigation window smaller than Sygic's full screen) Voice directions language is not configurable, it just uses system language, which is bad for me since I'm using English. It’s just to annoying to hear an english voice guide me thorugh Norwegian street names.

Sygic Aura

Sygic Aura has, by far, the best graphical interface in navigation mode. Menus are simple but functional, unfortunately it also has some issues with selecting the optimal route, but it does a better job than CoPilot. I don't like that I have to choose default route calculation in settings (Fastest, shortest or most economical), not for each trip, as it sometimes gives questionable route suggestions, and navigation through the city proved to be unreliable as it tried to guide me the wrong direction in a one-way street! Very good lane assistant, and information bar shows everything you need. Tunnel simulation is also very good. Voice guidance is the best of the three. Nice POI features, but slightly inferior to CoPilot. All in all it would have been my preferred solution, if it didn’t fail in route selection. (My hopes are that Sygic will solve navigation issues and add the possibility to choose optimum route before starting your journey) Please note that I used version 2.0 in this test. Latest version is 2.1.2.

Google Navigation is not available in Norway, besides, I don't have an unlimited data plan, so I am dependant on an offline navigation solution.

I have not tested extensively, so I cannot comment on how well these solution recalculates routes, integrates with phone features if you receive a call or performs over time. However, the short tests are done as similar as possible between the three, with the same routes, time of day, and with the same planned detours.

Conclusion

For now I will stick to Navigon, but I will not uninstall Sygic, as updates may fix the problems I experienced. The best from both would have been a perfect solution!

P.S. NDrive 10 was also briefly tested, first impressions was not good: User- and navigation interface was bad, even worse than Navigon in my opinion. Route calculation was similar to CoPilot, so not the best there either. I didn't like it at all, so I uninstalled after a short test drive.

P.P.S Heres is my other thread about SatNav software. No reviews here, but a nice poll
