I don't know if it's been mentioned in here, but I wanted to remind everyone about how to use navigation without using data. You can activate a cached copy of google maps via Labs and navigate with your data off. Just run your map, hit settings, select More, then Labs, and scroll down to pre-cache map area. Pressing on it activates it and then just follow the instructions on how to use it on your phone.
If you already knew this, never mind If you didn't, hope it helps
