GPS maker Garmin has released a free, mandatory upgrade for its GPS devices to correct a problem with a recent firmware update. After applying the firmware update, selected GPS models would repeatedly try to upgrade their firmware, then either fail to acquire GPS signals or shut down entirely. Garmin’s update, available via its WebUpdater, should correct the problem—but only for customers who can still power up their devices after the firmware upgrade. Folks whose GPS units have been bricked will need to request a return authorization from Garmin to send the unit back to Garmin for repair under warranty.

The Garmin GPS models impacted by the firmware glitch include the nüvi 7×5 series, the nüvi 800 series, the nüvi 8×5 series, the zümo 660, and the GPSMAP 620 and 640.

Garmin apologized for the firmware glitch. “We know our customers rely upon their Garmin GPS device(s), especially during the summer travel season, and we regret any inconvenience this situation may have caused,” the company said in its blog. “We are committed to developing products that are known for their quality and reliability and will continue to work diligently to earn the trust of our customers.”
