Getting lost while driving is never ideal. If your car doesn’t offer built-in GPS, though, it may be worth purchasing a mobile GPS system such as Garmin’s Nuvi 52LM. The slender device comes with free lifetime map updates for the United States and a rechargeable Lithium Ion battery, in addition to voice-prompted route and lane assistance with turn-by-turn directions and route avoidance options. The jet-black, high-resolution touchscreen also allows you to accept hands-free calls and packs a built-in microphone and speaker, along with multi-destination routing and the option to store up to 1,000 of your favorite locations for quick access on the go. Now through September 3, online discount retailer NeweggFlash is allowing you to save 33-percent off the initial list price of the Garmin Nuvi 52LM GPS, with bundled free shipping. Using your smartphone while driving isn’t the safest way to navigate — or even the most legal, for that matter.
