Conclusion: The Garmin Quest is the smallest in-car GPS system we have reviewed so far. Its portability and built-in battery make it an attractive choice for those that want to use the unit outside of the car.
Pros: Built in lithium ion battery, auto shutoff, small size, bright antireflective screen.
Cons: Somewhat unintuitive interface. Sound through cigarette-lighter adapter.
Summary: This tiny handheld GPS receiver includes maps, intelligent routing algorithms, an intuitive display, and can be programmed with custom data sources or integrated into enterprise applications. Quest is a good alternative to more complex location-aware platforms.
