The Garmin DriveSmart 61 holder is designed to stand on the dashboard. It is made for Garmin DriveSmart 61 (6.95 "display), but will fit other DriveSmart 6X and 5X with 6.95" display, but unfortunately not all.
To prevent it from sliding back and forth, it is placed on an anti-slip pad. DriveSmart 61 has physical dimensions: 173 x 99 x 19 mm. The holder also contains a USB holder and SD card holder.
