map/GPS app that preloads and caches?

I'll be in London for a week, and the roaming charge for data is sky-high, so I won't be connected except by finding free wi-fi. I know Bing Maps requires a data connection all the time. Is there another mapping/navigation app that would use GPS but let me pre-load the map data for London?

Why don't you use Nokia HERE Mapa. IT is offline.

Because I am one of the unhappy people who bought WP7 phones and then got royally screwed when MS decided we couldn't upgrade them to WP8. The Nokia map app requires 8. But, I could put it on my wife's phone, so I may try that. Thanks.
