PRE OWNED JRC NWZ-4570 JRC NWZ-4570 MARINE GPS

The JRC NWZ-4570 is a 5.7-inch monochrome STN LCD unit designed specifically for the professional bridge environment. It serves as the "brain" and visual interface for JRC's IMO-compliant GPS systems. Known for its high-contrast "Silver Bright" screen, the NWZ-4570 provides exceptional readability under varying light conditions, from the harsh glare of tropical sunlight to the complete darkness of a midnight watch.

The unit is more than just a monitor; it contains the processing power to handle complex navigational calculations, route management, and NMEA data distribution. Its rugged construction and tactile membrane keypad are designed to withstand the heavy-duty use characteristic of commercial shipping, making it a reliable standard for thousands of vessels worldwide.

TYPICAL CONDITION (USED/REFURBISHED)

Our refurbished NWZ-4570 units from Alang ship-recycling undergo a strict multi-point technical restoration. We focus heavily on LCD contrast and pixel health, ensuring there are no "dead spots" or fading. The keypad membrane is checked for integrity and responsiveness. We also perform a comprehensive test of the internal processor and NMEA ports to ensure stable data communication with external sensors. Every unit is factory-reset and provided with a detailed test report from our Bhavnagar facility.
