I used Waze today, driving from Yakima to Portland. Worked a treat. The UI is a bit like Power Puff Girls, but it was intuitive.

However, a couple of times, we lost signal and the app was useless. This wouldn't be a problem in an urban area, but in rural WA state, losing signal is not uncommon. I may try one of the GPS nav apps that store the data locally.

The other issue is that the constant GPS use sucks down the battery, by about 10% every 1/2 hour. If plugged into the car charger, with Waze running, the iPhone will only charge maybe 2-5% every 1/2 hour - i.e. the 12v charger will barely keep up with the power consumption. I'm going to look into more powerful 12v chargers.
