YD TEC was established in 2002 as a partner of Rostra Precision Incorporate USA. We had supplied cruise controls to GM Daewoo and SGM, also sold them in Korean automobile aftermarket. YD TEC also began rear view camera business as a front runner in co-operation with Rostra, constantly developing innovative models with state of the art technologies. Toyota approved the quality of our cameras and we have supplied OEM products to Toyota. Our products are selling in USA aftermarket with great review at this moment. We will always try our best to meet customers needs by constant quality management and development of new products.
