On a hot summer day, it's best to try to park your car in a shaded spot. But if this isn't possible, be sure to take with you or store personal electronics. Exposure to intense heat from the sun's rays can quickly deteriorate the lifespan of electronic items like smartphones and GPS devices. Unplug the items and place them inside glove compartments if you're away from the car for a short period of time; if you're gone for an extended time, bring them with you. Doing this one simple trick will help prolong the lifespan of these electronics.
