hey guys im pretty new to GPS apps on the iphone, but am seriously thinking of getting 1, browsed through the app store and saw two gps apps that's quite catching,

- papago
- tomtom

by price comparison, I'd prefer to papago as it's cheaper, just wondering, how does this work? they're both by satellites? means I do not need to activate 3g/wifi/data to start the navigation?

and another question is, after downloading the app, it's download-and-use or it'd require further registration/map downloading or so on so forth?

sincere apology if these questions are answered and asked before but really hope some1 cud help me out of this dilemma now. appreciate it. thanks

@wacky

Thanks for ur reply, another question, i tot iphone does not have garmin?

would I require separate hardware to be plugged into the iphone to use papago?

you do not need 3G/wifi to locate satellite..

Papago m7 pro has this function called 3D junction view which is a great help.. I'd recommend going for the pro version

Does this mean if i dun jb i wont be able to update the map of my paid ppg gps?

Ur method doesnt require jailbreak? Hmm

As far as im concerned, ppg does not consume data, because this app is satellite based.. Even when u start up initially ur start up location us determined by the satellite, so no data is required, i use my ppg app all the time, and im not on data plan.. And when i use it, i off
1.wifi
2.3g
3.data roaming
4.cellular data

And it still works!

yes ppg's layout sucks, but in the end, it's detailed enough to get me where i want to go, despite having never been to that particular place before. and also the fact that it uses MFM ensures that the maps and routes are always up to date (as compared to other brands).

in the end, would you prefer a pretty layout which lacks accuracy, or a bad looking layout but is always accurate?
