I took this navigation system in addition to my Google Maps to use when I don't have internet. Navigation is based on GPS, so you don't need internet. Nice, crisp screen, but the touchscreen could be a bit more responsive. Good driving voice guide and you can change voice accents and language. Navigation has other apps installed, including games. Easy to carry to wake up, but the battery only lasts 45 minutes, but you can plug it into the car cigarette lighter and no problem!
