Featuring plug-and-play design, OBDII Odometer communicates with vehicle's on-board computer to determine current vehicle speed and outputs real-time vehicle speed over RS232 serial data interface. Navigation accuracy down to 0.05% of distance travelled is achieved when connected to Spatial series GPS/INS products. Smart interface cable has built-in support for 9 OBDII communication protocols and can, depending on vehicle, retrieve speed from ABS or transmission.
