It can be used on a NAVnet vx2 only, if you use a PSU008 power supply between the processor and gearbox. Once the vx2 processor is connected to the PSU008 and RSB0072-061, the NAVnet system is designated as a 1964C(/NT). The NAVnet 1 didn't have a radar that powerful. The 1964C(/NT) was introduced with the NAVnet 2.
