VoxTrek for iPhone

[geraldteo]

I discovered this app for iPhone when I was looking for navigation apps that use data from OpenStreetMaps since I'm going abroad. It's a very handy and affordable navigation solution for iPhone but its drawback is that it requires an internet connection to load its maps similar to google maps. (I have a huawei e585 for mobile wifi so it's okay). You do have an option to download sections of the openstreetmap that's about 38miles squared but I haven't managed to get it working properly yet.

On the iPhone 4 it gets a signal very quickly and my navigation experience is good so far. The nuvi is still better though but it works very well for its asking price of 3 USD when you compare it to Papago for iPhone. There are many in-app purchases though (voices, extra maps) that run for 0.99 but what comes with the base 3 USD will already go far. (as long as you have a data connection)

Update: Seaching for POIs sometimes results in the app crashing.

Question lang - Do iphones support GPS? or just A-GPS?

If you're saying AGPS meaning it pinpoints the location using cellular data triangulation and a agps chip, then no. Since the iPhone 3g, the iPhone has been capable of GPS tracking without using cellular data. I've used the iPhone 3g on trips abroad where I cache maps using hotel wifi before I move out, I haven't been charged for cellular data during those times. Same limitations apply regarding clear view of the sky etc. Regarding navigation apps though, the 3gs and iPhone 4 models are more accurate since they also come with a digital compass. The iPhone 3g model relies on gps solely to pinpoint the location and determine where you are facing.

The first iPhone though does require cellular data to pinpoint your location. I hope this answers your question.
