A turn-by-turn voice navigation app is one of the most wanted app for iPhone 3G. xWaves had recently announced that they will be releasing an updated version of their xGPS for the jailbroken iPhone which will bring turn-by-turn voice navigation for the first time to the iPhone.
At the Mobile World Congress 2009, Sygic, a developer of navigation software for smartphones and PDAs demoed an iPhone version of their navigation software that includes turn-by-turn GPS directions with voice prompts, points of
interest, support for multiple countries and locally-stored maps.
Folks at iPhone blog who had a chance to see the iPhone app in action at the TeleAtlas booth at Mobile World Congress 2009 have reported that the iPhone app includes turn-by-turn GPS directions with voice prompts, points of interest, support for multiple countries and locally-stored maps.
Sygic's iPhone app uses TeleAtlas maps which are stored locally on the iPhone. So the advantage is that it does not need a data connection for it to work but maps would take up quite a bit of space on your iPhone. For eg. maps of Europe will take up 2 GB of space.
You can see some of the screenshots of the iPhone app below (courtesy folks at The iPhone Blog):
You can also watch the video of Sygic app running on a Nokia E90 to get an idea of how it works:
It will be interesting to see if Apple approves Sygic's app as iPhone's SDK prohibits "real time route guidance". But if it gets approved then it will easily be one of the killer iPhone apps as it will turn your iPhone into a true GPS device.
What do you think about Sygic's iPhone GPS app? What price will you be willing to pay for it?
