The Pioneer AVG-VDP1 Vehicle Dynamics Processor takes car performance analytics to the next level. The unit detects a wide range of real-time vehicle performance data — including acceleration, lateral G-forces, estimated horsepower, and torque, in addition to speed and RPM. Additionally, the GPS locator provides current vector information, as well as current location by longitude, latitude, altitude, and distance to destination. The unit displays the results on a connected Pioneer Audio/Video monitor — with smart, full-color graphics that add style to the dashboard.
