A NEW GADGET FROM GARMIN: The Garmin nuviCam LMTHD is a combination dashcam, GPS, lane departure warning, and collision warning device, all in one. “The $400 GPS device features a 6-inch touchscreen with pinch-to-zoom and Garmin’s free lifetime map updates, as well as Garmin’s HD Digital Traffic with real-time traffic updates every 30 seconds. The navigation system is voice activated, and can predict time delays or find detours when you’ve hit a particularly nasty traffic snarl. But the nuviCam’s biggest trick is what you’ll find on the opposite side of the GPS screen. A built-in HD dashcam that continuously records, and saves a timestamped video with GPS location data if it senses an impact. The camera records to a 4 GB microSD card (included), and can even take photos—say, to document damage or capture license plate photos in the event of an accident.”
