Garmin just released StreetPilot for iPhone, the newest addition to their mobile line-up of GPS apps. The app boasts a lot of the same features nüvi owners already enjoy. StreetPilot has up to date map support for both the US and Canada. All maps and directions are pulled from Garmin's servers so you can expect the same quality directions as a native GPS unit. Since maps are pulled from the server, the app only takes up around 7 MB of space on your phone. Hit the jump for a few initial impressions, some screens, and a list of features.
