The Garmin Dash Cam 20 with GPS is an easy-to-use high-definition driving recorder with 2.3 in. LCD display. It records both audio and video with GPS, for detailed time and location data pinpointing exactly where and when events occurred. Mount the camera to your windshield and record your drive in 1080p, 720p or WVGA. The unit records in a continuous loop, using the included 4 GB microSD card. To add more memory, add a larger microSD card (accepts up to 32 GB, sold separately. Class 10 required). Play back the footage on the LCD display or review later on your computer.
