For those who aren't interested in Sygic, you can use:
Waze (free)
Google maps (free)
Apple maps (free)
Tomtom (free for first 80 or so kms)
Sygic is fairly well respected in the IOS App Store (2247 people rated it an average of 4.1 out of 5). Has nice features like lane guidance, speed cameras, crowd sourced radar information and live traffic (if you include it in your lifetime purchase).
If I didn't pay for Sygic, I'd probably recommend Waze. However, in South Australia, Waze is not reliable and frequently directs me the wrong way, even on basic trips.
If anyone has feedback on Sygic, please share it as I've only just started using it.
They could definitely improve the searching, it's the biggest letdown for most people.
