As if Garmin wasn't having enough trouble selling GPS units in an increasingly smartphone-driven world, now it seems roughly 1.3 million nuvis are at risk of overheating -- possibly "lead[ing] to a fire hazard!"
Garmin is voluntarily recalling around 1.3 million nuvis, including some 200W, 250W, 260W and 700 series models. Not ALL units are affected, however. Only units manufactured within a certain date code range are impacted. You can use this form to enter your nuvi's serial number and see if it's part of the recall.
If your nuvi is part of the recall, Garmin will replace the battery, and insert a spacer between battery and the circuit board free of charge.
