If not HTC buys Jolla....
HERE is pretty damn good these days on Lumia.
it's basically the same thing IMO. the UI design is a direct rip of the N9s. they just added a few things (basically those hidden codes we found for the map mods). it still doesn't take into account traffic conditions, it only has the ability to show the conditions. but overall, the application is faster and more accurate. but symbian still one up's it with the ability to route around traffic.
