Volvo is recalling all models equipped with Garmin 760 Portable Global Positioning System units because the battery may overheat, which could lead to a fire. Volvo advises owners to stop using the Garmin device immediately and consult the Garmin website to determine if they have a defective unit. The unit's battery will be replaced and a spacer inserted to prevent the problem from reoccurring. This will be performed free of charge.
