I'm an Android HTC user, pretty much tried every mapping tool out there. Some topo products are pretty good and there are decent on-device street navigation tools as well.
However, I still find that simply scanning way ahead and all around my destination area with the default GPS/Mapping app will cache everything pretty well. I just give myself a really wide berth to account for any route changes. Once the scrolling/caching is done and any internet mobile/WiFi shut off, it works fine
I also do this for GPS navigation in the UK as I go there for work a lot, and drive extensively. I just do the cache trick using the heathrow airport WiFi then turn off all internet access, keep the GPS on, and I'm good for driving pretty much anywhere.
