Today, Garmin released a free, mandatory GPS software update to correct a software issue that has been discovered to cause select GPS devices to repeatedly attempt to update GPS firmware, and then either shut down or no longer acquire GPS satellite signals. The products affected are the nüvi 7x5 series, nüvi 800 series, nüvi 8x5 series, zūmo 660, GPSMAP 620 and GPSMAP 640.
Garmin nüvi 7x5 series products that are no longer able to acquire a GPS satellite signal may download a firmware update immediately that will correct the software issue. This firmware update may be downloaded using Garmin's WebUpdater program at http://www8.garmin.com/products/webupdater/howtoinstall.jsp.
Firmware updates for other affected products will be available online through Garmin's WebUpdater in the near future. Affected customers who have registered their GPS device will be notified about these updates through email.
Garmin nüvi 7x5 customers who are no longer able to power on their GPS device will need to visit www.garmin.com/support, and select the first FAQ titled "My nüvi 755T, 765T, 775T or 785T is giving me the message 'Updating GPS Firmware' or will no longer power on..." Customers will then need to follow the instructions to request a return authorization so that the device may be repaired under warranty.
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. 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.
