Conformal Coating
Conformal coating is a special film that protects circuit boards, components, and other electronic devices from adverse environmental conditions.
It provides increased dielectric resistance, operational integrity, and protection from corrosive atmospheres, humidity, and airborne contamination such as salt-spray, dirt and dust.

Short Chassis Design
An digital media receiver unit is the ideal head unit for your car if you no longer use CD's as a music source. The total chassis depth can be reduced by designing a head unit without CD mechanism. With digital media receiver shorter in depth, installation is made easier in a wider range of cars.
