Road Test: AT & T Navigator GPS application iPhone
I just finished testing App GPS-Navigation, which offers all those previously unavailable features: AT & T Navigator (version 1.2i.5). The catch? It has no built-in maps (ie, you need a working data plan to download maps in real time), and it requires a monthly subscription fee of $ 10. App itself is free.
This is one of the first GPS navigation applications made for the iPhone. In fact, this product TeleNav and available to other cell carriers, including Sprint and Alltel.
Unlike the other aforementioned applications, which take an hour or so to download using Wi-Fi, AT & T Navigator has built-in maps and, therefore, a snap to install on the iPhone, even over 3G or Edge connection. This makes it the perfect complement to fast, when you suddenly need a navigator GPS.
App also launches very quickly, taking only one or two seconds on my iPhone 3GS. When she can (more on that later), it also raises the GPS signals very quickly. About a week of use, I can say I really like the real-time update Traffic - that warn you both on screen and hear - and convert text to speech features. This is especially useful when you are in an unfamiliar city.
However, I found that the movement updates are available mainly for highways only, unlike Google Maps, which give them all the way up to the streets of major cities.
Converting text to speech is particularly important because it is a few for lack of AT & T navigator lane assist, a feature of most other GPS applications I tested the proposal. AT & T Navigator just does not show you a map strip of the opinion that to take in case of multiple exist or freeway merging such a hearing the street name or exit to read aloud is vital.
App is well integrated with your contact list iPhone, but it might take some time (up to 10 seconds or so) to read the address, because it must communicate with its internal server to find the address and routing in real time.
This message is the source of many problems. First of all, this means performance at the mercy of AT & T data signal, which - let’s be honest - it is a schematic at best. When there is no signal data, see the map just freezes and the car icon (representing the current location), just stuck in one place. There is no indication of what is happening either on screen or via audio. This happened three times in a short trip around the Bronx at the airport JFK.
The second question, the application is that it seems largely unable to get a GPS signal in the dense parts of big cities - in my case, both in Manhattan and in downtown San Francisco - apparently in connection with skyscrapers. I found it interesting because, although the application can not get GPS to route the signal, she was able to display my correct location (point, similar to a Google Maps) on his map.
Now here’s the dilemma: the application has no problems collecting the GPS signal in space, towns, or in the suburbs, but in larger cities, where you have an extension of the data signals, especially 3G. So it’s no better place for the application. Fortunately, the application works relatively well, even if 3G is unavailable. Where it is not, everyone, including the route, took a little longer to happen, and if you drive too fast, see the map can not be updated quickly enough to show you everything.
To compensate for this, AT & T maps and POI, a very recent date. (During the construction phase closure Bay Bridge at the weekend to Labor Day, TeleNav even made routing application automatically excludes the bridge.) You can also dial-up point (POI’s) phone number of interest simply by touching it.
In general, although I really like the text to speech function, update maps and POI, and real-time traffic, while AT & T get better data coverage, AT & T Navigator is not an option you can rely on. Now it is a much better understanding - and ultimately cheaper - to go with the app with built-in cards, such as Navigon and TomTom.
