UPDATE: This model has been replaced by the nuvi 42LM (49 states) and nuvi 44LM (US + Canada).
The Garmin nüvi 40LM is a 4.3” navigator in Garmin’s new 2012 Essential series. The models in this series are meant to be basic navigators at a budget price, lower than what we’ve previously seen for Garmin entry-level models. Nevertheless, they do come with some features not previously found on low-end nuvis, such as speed limit display, lane assist and junction view. And the 40LM includes lifetime map updates.
