Review: MapFactor GPS Navigator
(All About Windows Phone)

It`s a fair cop - MapFactor GPS Navigator isn`t new and is in fact a Windows Phone 8.1 application. But - interestingly - it uses bang up to date OSM (Open Street Map) err.... maps. Which, as I ranted recently, doesn`t apply to Windows 10 Maps, which are missing recent roads. So is this worth using instead?
