Detailed Product Description

With transmitter built in ECU and receiver in display, ECU transforms signals from
sensors into digital data and sends to display via radio frequency. No cable isneed any more between ECU and display.Audible distance indication: 1) 1.50 to 0.80m: Bi, Bi, Bi 2) 0.80 to 0.40m: Bi, Bi, BiBi (the closer, the faster) 3) 0.40 to 0m: Bi...
