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. The small screen is bright and good to see even in sunlight, but we found the interface somewhat difficult to use.
Pros: Built in lithium ion battery, auto shutoff, small size, bright antireflective screen.
Cons: Somewhat unintuitive interface. Sound through cigarette-lighter adapter.
