That's what I've been doing, using my iPhone and MapMyRide.
Still with a phone you need reliable cell service to connect to either Google Maps or MapMyRide, so I was looking for the next level up, something that would work independently (no data plans, no dependency on cell towers, etc.).
Don't use these, then!
You can get apps that use local maps (downloaded before-hand).
For the iPhone:
Motion X GPS lets you download maps easily and tracks (but doesn't provide turn-by-turn).
Motion X Drive lets you download maps (
but not easily) and provides voice turn-by-turn for an extra monthly fee (I'm not sure if this is worth it). It looks like "Drive" will cache the maps for a computed route (which doesn't seem that useful for your purpose).
