The 2.5.6 links above don't work. Its the European version and comes without maps. I already tried that version and gave up as the bundled license I'm assuming only works Europe maps.
I did however manage to find an older v2.3 for IOS

In my case WhereIS Australia 2015.03 worked for me.
Just took this for a test drive. Whilst the app runs great, I found 2 problems with it. Hopefully someone can upload a later version of this app that may fix these problems.
1) Phone keeps going to blank/lock screen after amount of inactive time set in IOS ie Setting > General > Auto Lock
Only way to fix is to set Auto Lock to Never.
2) Primo not saving settings. Keeps running Configuration Wizard on startup if application is removed from memory or phone is restarted.
