Function and Setting Instructions:

- Origin -
KOSO was officially established due to the recognition that an independent self-developed brand is indispensable for future market marketing. Therefore, in 1989, KOSO was registered as the trademark for Tong Ya. KOSO originates from the Japanese words "kousou" (conception/idea) and "kousoku" (high speed). Conception signifies creativity, and high speed represents high-performance output. Combined, it expresses the company's aspiration to create high-performance products through creativity!

- Spirit -
The brand spirit pursued by KOSO is to build quality, technology, and service on the foundation of integrity and mutual trust. We persistently uphold this attitude, not only manufacturing high-quality products but also pursuing product innovation and quality improvement, aiming to bring more excellent products to everyone.

- Brand Journey -
Striving for perfect product design and quality has always been our goal. Therefore, KOSO continuously pushes itself by enhancing its technology. We firmly believe that brand image and product quality are synonymous! Consequently, the company has stringent requirements for product development, production processes, and quality control, aiming to achieve high-quality standards while stepping onto the world stage. In the future, KOSO will continue to develop more user-friendly and innovative products, aspiring to become the next world-leading Taiwanese brand within ten years, another pride of Taiwan, and a source of pride for the Taiwanese people.

- Exhibitions and Certifications -
Tong Ya Electronics began exhibiting in Italy in 2001, gradually stepping onto the international stage and bringing KOSO's dedication and professionalism to the global market, while striving to convey an image of high quality and innovation. In 2007, we obtained the TS16949 international certification, and in 2024, we obtained ISO 14001 and ISO 45001 international certifications. We will continue to create products that resonate more deeply with users. Every product launch requires actual installation testing, which is the most rigorous quality inspection method. Regardless of how well a product is designed, its quality is tested once it is actually installed and used. To further enhance quality and product testing, we participate in international competitions, and each award is a testament to our products' quality, as it allows for no room for error in modification or installation. We are this meticulous about quality. Test reports and product measurement charts are also demonstrations of our installation results for customers. It is precisely this diligence that allows our products to exhibit progressively better quality.

※The vehicle model may have different specifications in different regions and may not be compatible for installation.
