Hands on Garmin nuvi 52LM review. The Garmin nuvi 52LM is one of the company’s 2013 Essential series models, and while considered an entry-level device, it includes features such as speed limit display, junction view and lane assist – things that were relegated to high-end models not that long ago. It’s a great choice for someone who needs a basic navigator without the bells and whistles.
