Bit the bullet & paid over $30 for a Windows Phone app today. I recall using Sygic GPS Navigation, etc as a 7-day trial when I used the Lumia 1020 but did't continue with it as it didn't offer much more than Nokia Here Maps & Here Drive+. The Here series of apps no longer work in WinPho 10, Microsoft Maps navigation features are feeble at best.
I tried a number of the available apps but none are a patch on Sygic. I'm afraid the WinPho version of Waze is a feeble & crippled piece of shit when compared even to its Android version, let alone the iOS variant.
