On-dash integrated information display

The 4x4 Altimeter on-dash integrated information display is a perfect match for any adventure on harsh and uneven terrain, providing data on the orientation of the vehicle (pitch angle, roll angle) as well as its speed. The bright display features an electronic compass for navigation and a light sensor to automatically adjust the device's back-light in line with the brightness outside. Since the altimeter connects via GPS, its speed, location and time measurements are far more accurate than could be achieved with the OEM vehicle read-outs and provide the driver with the information they need on any excursion.Features & Functions:> Integrated speaker> Volume +/- & mute> Power on/off> Light sensor (automatically adjusts back-light brightness relative to outside brightness to reduce glare)> GPS icon (will show when successful GPS connection is established)> Current time (hours/minutes - automatically calibrated by GPS)> Voltage> Vehicle speed> Pitch angle> Roll/tilt angle> Elevation> Temperature (internal)> Electronic compass (calibrated by GPS)Specification:Pitch Angle: -40 degrees - +40 degreesRoll Angle: -40 degrees - +40 degreesTemp.
