Portable navigation device maker Garmin has recently publicly acknowledged the issue with its nuvi 7x5-series devices that causes them to shut down. Calling it a firmware error that causes some devices to perform an unprompted GPS software update and in some cases shut down, Garmin announced it is "working diligently on a solution." Users began reporting the shutdowns earlier this week, leading many to believe the error originates from a new firmware update.

The high-end 7x5 series of PNDs from Garmin was introduced in August of last year. All have a 4.3-inch touchscreens along with lane assistance capability, Bluetooth, FM traffic and MSD Direct traffic optional on some models and standard on others. Pricing ranges from $400 to $550. [via Twice]
