I use Sygic (pay once App. and free updates forever) on my iPhone and I'm very happy with it. BTW via iCloud my iPad and other iDevices all get the same App free. So, I can and do use the Sygic app on my iPhone all day, for work, but use the iPad on 'weekend' trips, etc. once downloaded all the maps are saved offline so I don't have any data charges when I use it driving around. It's not perfect by any means, but it's 100 times better than my old dedicated GPS device. Funny, I've got the new iPhone and my wife has the new Samsung. I hate the bloody thing (S4) and my wife won't touch the iPhone for love'nor'money... Curious creatures, we all are.... In the car I have a power cable, so my iPhone is always fully charged... No problem. BTW, you need a power cable to keep charge up whilst using the Nav. apps.... They drain batteries real quick... Edit: I should mention my App has full voice, turn by turn directions. The latest update included the road works through Springwood, which are still under construction (very up to date info) and quite a few new speed and red light cameras I was unaware of. (Did I mention ALL updates are free) In addition it has either a 'walk-to' or 'drive-to' function? I've used the 'walk-to' function around places like Toohey Forest, Glasshouse Mountains, Straddie, Brisbane CBD, etc, etc. and it sounds quirky, but trust me, once you use it you will really appreciate it. Recently, at places like Rainbow Beach and the border range waterfalls... Well there's a function where users can upload photos of 'special sites', I dunno, unusual flora and fauna, natural features not otherwise documented, etc and the location which Sygic will take you right up to. We 'found' some really amazing 'bonus surprises' by using this fantastic feature. There is also the option of subscribing to live traffic updates, but I've never bothered. These Apps and the additional features that are so easily used make your experience so much richer that they are really on a much higher level than your basic car based GPS. Much cheaper toooo....
