The HERE Drive+ is designed specifically for in-car-use (to work as standalone satnav replacement), but they also have "HERE Maps", which will give you public transport and walking directions: http://www.windowsphone.com/en-us/store/app/here-maps/6c2863...

What is available for the cn market? My phone is locked to that even though I'm American myself.

I was use ping here maps, or HERE whatever, there are a lot of them and I'm not sure what each does. It didn't help me find something as simple as the post office when I needed to mail off tax forms last month, which google maps and apple maps had no problem with. Very disappointing.
